I've got two cousins born a month apart that are getting into mid-teenage years. One a girl and it was really odd that even as a 4 and 5 year old we got along. Usually little girls drive me nuts, but she's a bit of a nerd so there was that in common too. Got a couple years into school and then the school talked her parents into putting her on mind drugs for whatever disorder they came up with. It was like flipping a switch and now she's a weird zombie most of the time. The other cousin was an annoying little brat in pre-school age, always been homeschooled, and is now one of the more normal acting kids I've interacted with that age.

I used to think homeschooling was stupid, but I turned on that about 10 years ago and now if I do end up ever having kids they will not be going to school.
