Asperger's

My son has Asperger's and he is very very quiet at school. He has two friends, neither of who attend his school. For the most part he goes through his tiny high school with his hood up on his hoodie and (if not in class) his face buried in a book. He is nearly unnoticeable at school and if he attended a large high school he would probably be invisible. We were joking about his invisibility when he said "I don't want to be invisible in college, I'll need to be noticed." I said "Well then you'll have to talk to people." He responded "Gosh darn it, there's always a catch."
