Yes and yes!
My son is very comfortable talking with adults, although he can be long-winded at times. He does really well with young kids. Same-aged peers are seriously difficult. Things are better if the other child is "gifted" and same age.
Taking turns in games is not too difficult, but following the rules is.
My son is willing to follow the rules, but as games progress and other kids abandon or change the rules, my son cannot tolerate the situation. He sees it as very unfair. So, he usually avoids playground games at recess. Creates much less conflict.
