Nothing feels more satisfying than having baseless anger validated. It's why you smile when a politician you don't like gets caught up in some terrible scandal. It's one of the weirdest evolutionary developments to happen to the human brain. A new co-worker shows up at the office, and you make a split-second decision that you don't like him. Something about his face or the way he speaks or dresses fills you with venom, but you have no reason for having all of that animosity, so you keep quiet about it. Suddenly, you hear a story about this person leaving a mess in the bathroom, or finishing off the last of the coffee without refilling the pot, or drinking too much and acting rude at a company function, and then a part of your brain lights up and whispers Yes. We were right. We were right to hate this person, and now we don't have to be silent about it anymore. Now our hate can focus and burn bright. Yes.

[Real Talk Alert]
I get that way. I get angry a lot. I have a short temper. I'm always ready to fight. More than anything, I have rules. I have a strict, very black-and-white set of rules in my head, and if someone breaks one of those rules, even if the rule is stupid, even if I've unconsciously broken that rule myself in the past, even if I never explained the rule to anyone, I will hold a grudge. Passionately. I'm great at it.
