Trust me, your son is fine. You know what I did yesterday (Friday night)? I stayed in my room and watched movies and went on my computer. I was very happy. All the rest of the college students were out partying. I was perfectly content being away from all that noise. I hate going out, especially with peers. I don't see the point in it. You have to work around them, when it's far better to just be by yourself doing your own thing. I even eat by myself 9 times out of 10 because, that way, I don't have to worry about waiting for people to arrive or waiting for them to finish eating when I want to leave and not have to talk, and I can do my movie quotes or talk to myself when I eat by myself. It's an ideal situation. My mom often worries just like you. "Did you eat with somebody today?" "No." Once in awhile, I'll eat with one of my two peer friends, the one who has mild Asperger's, because he hates sitting around, too, but I only do this when we get together to watch a movie or something. This happens a couple times a month. I almost never leave my dorm room on the weekends. I literally have left my room once today, and that was simply to go to the bathroom. Am I bored or lonely? Hell, no! I am my best companion...

If you have any questions, feel free to ask. I'd love to try to help you understand. If I recall correctly, your son is the one who also likes to talk to himself and draws in the air? Your son and I seem to have a lot in common.
