are you anti-social?

I am not really a people person. i don't know if i would go as far as to say I am anti social though. I have no problem talking to people I encounter on a daily basis like at the post office etc but I don't really enjoy being around people I don't know really well. I love to be around my husband and kids but as far as having to go out and be social I am not that way. I enjoy going out to dinner and the movies with my husband but as far as going to bars or things like that and interacting with a-lot of people I really don't care for it. I really don't like visitors either. I just like to be in my own home with my family and no one else. I don't know what makes me tick I am just a loner. There is a guy at the shelter I sometimes volunteer at that is very much anti-social if not socially retarded. He backs away from anyone that speaks to him like he terrified and when he does speak you can tell he is not very comfortable at all with speaking in general. He always has headphones on and really cannot have a true conversation with anyone no matter how nice you are to him. I would say he is more anti-social.
