Basically, they often just cannot find a balance between the two extremes of getting out too much and not getting out enough. That includes myself.
This can get especially confusing when the autistic child is in high school, when fishing for friendships is the ultimate concern of the entire community. Your lifelong best friend from kindergarten finds an interest in the life of drugs, and you two end up drifting apart. You feel a romantic drawing to a girl in the math society, but your social clique forbids interaction with that group. You want to come out as gay, but you’re afraid of all your closest friends turning against you. These are confusing times for anyone. Even more so for the autistic individual.
