I can relate to this. Since I was a kid I can remember sitting outside at bible school and watching all the other kids play and wanting to be close and involved but I would just sit away from everyone and do my own thing. I even remember a teacher trying to get me involved and I screamed and pulled away in tears... I am not quite so bad anymore but it's still hard for me to leave my house and I only have one real friend in real life. I am okay with it, but I feel like I offend other people when they want to get together.
