Here's the thing: I am not willing to change my schedule for a baby. I know that makes me sound like a huge dick. I'm basically saying that I could never love anyone enough to become a morning person for them. But, it is about so much more than that.
I love sleep. Loooooooove it.
I love letting my day unfold how I want it to. I can go out or stay in. I can drop everything and go to lunch with friends (a lot of this also has to do with my job, but your terrible career choice is another article entirely.) The point is, I like having complete control over my schedule. I don't want my time to be dictated by a tiny, screaming sociopath who can't even talk yet. To most people (including the Pope), this makes me a selfish b***h.
And there are so many more areas of life to be selfish about! I don't have a lot of money right now, but I might one day. And when given the choice of spending it on private school and whatever the 2020s version of a Furby is, or blowing it on vacations in which I can sleep in new and exciting places, I'm going to go with the latter.
