When You're a Kid:

One day a year, kids get to dress like their favorite fictional character, walk around at night as they're told never to do, and receive candy for free. That's the Shangri-La a child would hallucinate and reach toward right before they pass out from a sugar rush in a world where Halloween doesn't exist. It also kind of sounds like a pedophile's perfect world.

When You're an Adult:

Halloween takes a turn away from costumes and spookiness when you reach the age where time spent working and sitting on your ass for eight-plus hours a day leads to an increase in laziness and pant size. Only kids can slam that much sugar in their heads and not end up feeling like a fleshy Katamari ball that propels itself with directional thrusters made of burps and farts. Halloween for adults becomes the one time a year a so-called "responsible adult" has something that somehow resembles justification for buying candy by the pound. Kids might show up! The candy must be purchased for the appeasement of the kids!

You.

There ain't no kids. OK, maybe one party of an Iron Man and a kid dressed like a modern-day sexy vampire, but not enough to justify what appears to have been your cut after an armed robbery of Willy Wonka's factory. After months of restraint, months of holding back your most gluttonous, base instincts to slam every junky piece of candy within sight into your body, and months of using every excuse your brain can muster -- from weight gain to health risks to cavities -- there comes one day with a built-in pro-candy argument so convincing it obliterates every excuse you've got. Halloween is about candy, and if you don't buy candy you're technically a joyless a*****e.

"Candy. Candy. Candy. Halloween. Candy. Candy."
*standing ovation from jury*

And so, the day has changed. The candy used to be the treat your parents would allow you to gorge on for a small window every year. Now, the candy is the self-flagellating shame filth you shove in your sopping, gaping maw like Gollum in the fetal position in a dark cave holding the ring after weeks of ring withdrawals.

Whether Santa is still real in a kid's mind or not, the magic of Christmas is real. The whimsy of the day is real. The unbridled, child-like innocence is real. And it's all mostly caused by the totally awesome toys and video games you get to unwrap on Christmas morning. Let's face it: materialism is kinda fun.

When You're an Adult:

Almost no gift received on Christmas day as an adult will bring as much joy as the gifts from a childhood Christmas. There's so little an adult could want that can bring out the same level of the nearly chemically induced mega-joy of a kid unwrapping a Ninja Turtle action figure, or a Nintendo 64.

Adult Christmas is mostly a bite-your-lip-and-bare-it affair. Maybe someone will splurge and get you an iPad, or even a PlayStation 4, and you'll jump for joy when you see the packaging as you rip away the wrapping paper. But assuming you have a job, there's a good chance you've already bought those things for yourself. A job and a steady cash flow take all the surprise out of Christmas gifts. You've got most of what you could want, and you bought it seven months before Christmas because who's going to stop you?

So what's left to surprise you? Your loved ones have nothing to pick from other than the crumbs and scraps of your interests. Their shopping list has been whittled down to all the things that you've passed over on store shelves on your way to buying the things you would have been given for free if you would have waited a few more months.

In the end, it's not at all a bad thing. Christmas as a kid is like eating an entire unsliced pizza in one sitting. As an adult, you're slicing it into equal triangles and eating it as needed. But clearly, one of those is way more fun than the other.

When You're a Kid:

Fireworks. That's the 4th of July as a kid. It's the id of the American holidays. It's primal. s**t blows up, and we cook dead things over open flame. Children are a loincloth away from being feral anyway, so the 4th of July fits right into what they expect out of life. Unlike the other holidays, where magic and whimsy play a big part in our pleasant memories, the 4th of July is all danger. It's stories of cousins blowing their hands apart, uncles too drunk to realize they're on fire, and massive Roman candle shootouts that make Harry and Voldemort casting spells look like two losers waving sparklers.

When You're an Adult:

The id remains, it just shifts focus. Fireworks are still there. Just now they aren't as fun. The novelty of exploding colors has worn a bit. But there is one way to make them fun again, a way that only adulthood can offer: getting rip-s**t drunk. The priorities of July 4th are restructured, and now getting wasted on America's birthday is more important than cooking the dead over flame, watching things go boom, and America itself.

It's not a very well-defined holiday. There's not much built in to it that tells us how to celebrate it. On Thanksgiving you give thanks. On Halloween you be spooky. On Christmas you Jesus. But how, exactly, do you celebrate a landmass? Presumably, it went like this: with no built-in rules of celebration, we drank to get our creative juices flowing to come up with a good idea, and then drank more, and then drank again. After a few drinks we said, "f**k planning -- let's get wrecked. Hey, who's got a cannon we can shoot at the sky?"

Oooh. So that's how they make fireworks colorful.

Just like sacrificing a goat or a virgin to appease a god was standard fare for primitive cultures, looking at an American flag and occasionally tipping a can of Coors at it as a sign of respect for a cheap thing from China made of low-grade napkin cloth is the American version of a high honor. It's the best we've ever come up with -- and it will never be beaten; we're too drunk to try.

When You're a Kid:

THE FOOD! THE INCREDIBLE, EDIBLE BOUNTY OF FOOD! THE HEAVENS HAVE OPENED, AND THE GODS HAVE BESTOWED UPON US A FEAST UNWORTHY OF SUCH COSMICALLY INSIGNIFICANT CREATURES AS MY FAMILY! OH, WHAT FLAVORS WE SHALL FEAST UPON! WHAT TEXTURES WE SHALL SAVOR! THIS DAY, THIS DAY OF GIVING THANKS, SHALL FOREVER BE NOTED AS THE DAY MERE MORTALS WERE GIVEN THE BRIEFEST OF SAMPLES OF THE ENRAPTURING TASTES OF THE UNKNOWN WHICH LAY BEYOND THE REACHES OF THE MINUTE SLIVER OF TIME AND SPACE HUMANITY CALLS HOME!

The green bean casserole still sucks, though.

When You're an Adult:

Candy comes a very close second behind dressing up in a costume when ranking the most important parts of Halloween. For July 4th, grilling is third behind basking in the majesty of the U.S-f****n'-A and watching colors explode without the need of a hallucinogen. So of the major American holidays that heavily involve eating, Thanksgiving is the only one where eating is the primary objective. Thanks are an afterthought, and who the f**k gives anything other than no fucks about caloric intake on Thanksgiving? It's all about the meal -- pure and simple. That puts a lot of pressure on that meal. This bounty is going to happen only once a year for most families -- better make this s**t count.

This turns adult Thanksgiving into the food version of The Raid -- it's a vicious, violent gauntlet of food. It's the one holiday that feels most like a dare that should be recorded and uploaded to YouTube so it can spark an Ice Bucket Challenge-type meme where people defy one another to consume until they are physically uncomfortable and in a catatonic state of shame-induced psychological ruin.

He's looking at Thanksgiving.

Leftovers can be eaten, but that meal -- that assortment of flavors and textures, all giving off an inviting warmth that begs to be taken advantage of the moment it's served -- has a small window of maximum enjoyment. You have to eat it all now, while it's hot, fresh out the oven, or it'll feel like a perfectly good non-denominational day off has been wasted.

Thanksgiving isn't a holiday anymore; it's a plate of food slapping you with a glove and calling you a p***y.

It's like modern-day hype for a movie. The excitement builds in the lead-up, which culminates on opening day, and then there's all that residual glory lingering around that's released by telling everyone how good the movie was. If a kid could camp out and wait in line for months for their birthday the way mega-fans camp for Star Wars, they'd do it -- and our streets would be littered with filthy, excited hobo children.

When You're an Adult:

Who gives a s**t? That's how to best sum up an adult birthday. It doesn't matter. Last year, a friend and I talked on the phone for 10 minutes on my birthday. Two days later he called back and apologized for not having said happy birthday. I didn't notice, nor was I aware that it was my birthday during the conversation. Birthdays are just days, and then there's cake. That describes most days for most people.

Facebook has become an alarm clock for birthdays. The only time I'm really aware it's my birthday is when, suddenly, people I've never told my birthdate and know almost nothing about me wish me happy birthday because HTML coding told them for me. If I were to set the date to any of the other 364 days of the year, most of my Facebook friends would think that's my birthday. That would be a funny joke to me, until the moment I get confused and think March 3rd is my birthday. f**k March 3rd. That s**t isn't my birthday. That's what an adult birthday gets reduced to: countless reminders on social media from people who were told to say happy birthday, and from every website you've ever had to give your birthdate and email to in your life. It's so uneventful people need reminders.

I didn't know what image to put here, so I typed "stupid" into a stock photo site and this came up. You're welcome.

Childhood birthdays felt like I leveled up my character in a video game. There's a sense of having ascended to a new, more powerful echelon. Every adult birthday is the moment when you realize the game developers didn't fully think through character Levels 40 through 50, and every energy blast feels about the same. Yeah, I can kill a lot more bad guys than I could at Level 5, but I've peaked. The numbers will keep going up, but I'll never feel that leap in ability again. Or, to put it in the words of Private First Class William Hudson:

Despite what he wrote in that last entry, Luis would genuinely like to thank his social media friends for wishing him happy birthday last week. You can too if you follow him on Twitter and Tumblr.
