Are you familiar with asynchronous development? It is not unusual for a gifted child to develop much faster than normal in some, but not all areas. For our ODS, this expressed itself in being somewhat socially "immature" until very recently (he's 10 now). Although he could handle schoolwork at an advanced level, he wasn't likely on "age-grade norm" level in some social aspects. This has changed as he's aged. Just something to consider, particularly if he's young for grade. You may be seeing quite normal social behavior when you take asynchronous development into account.
