How can i deal with a person who has aspergers?

A few ideas: These people are different. They miss social cues, can focus intensely on single subjects, do better at strength & endurance sports rather than coordionation / team sports, and seem strange and antisocial. Don't try to change the person. Tell them how you feel ("I like it when you.... I don't like it when you....") They may be grateful, as they know they are often jerks without meaning it.
