Autistic people vary enormously from each other but they all find social interaction difficult.
For example, some autistic people:
Are unwilling to make direct eye contact with other people
May not respond when their name is called or when they are spoken to
Are unaware of social conventions/appropriate social behavior. For example they may not understand the importance of taking turns during a conversation.
Are indifferent or averse to physical contact and affection. For example, they may not like being hugged.
Prefer solitary activities and do not try to make friends or would like to make friends but don't know how.
