Why do I not "fit in"? Can I be a snob?

I have always had older friends too. The thing for us was that our parents were drunks and addicts, so we had lived more life by 12-years-old than most people did in their whole lives. We didn't play with other kids, we had real life issues to deal with. We could relate better with our teachers than our clmates. I don't think it makes you a snob, you have to be friends with who you are comfortable with. Just be yourself.
