Don't know if it is connected to Asperger's or if it is just my personal quirk, but something I've noticed is that I actively prevent my different circles of... friends (better: acquaintances) from overlapping. I got my college "friends", my hobby "friends", my friend friends, my other hobby "friends", my other hobby "friends", and some internet friends, and I go to great lengths to prevent them from getting introduced to each other. I think it is because I put on different facades in each of these circles, not to become accepted, but just to not stick out too much. When two of them overlap, some behavioural patterns I have adopted in each circle individually tend to collide, and this confuses me and causes me to make a fool out of myself. People have been telling me that at times, they find me to be frighteningly manipulative, as I plan and arrange meetings and other things so there will not be any mixing between two groups.
