Have you grown up like this? I have. It's a lot more alienating than you think. In my case it was a religious upbringing with little outside cultural influences, and it does make it hard to interact and socialize with others.

You don't have shared experiences or languages. There's usually only a small amount of children who share what you experienced, and you don't always understand when they are joking, or how to deal with situations, or even what they are saying. And many times the kids you do know are weird or worse than those your parents think they are protecting you from.
