Yes, I think that this is actually a life lesson that astonishes some people as young adults-- when they realize that agemates and accidents of geography and bureaucracy aren't necessarily the ingredients of true friendship.
Gifted kids (and especially at higher LOG) learn this one and all its nuances quite young. Friendship is about shared interests, yes, but is also about a certain amount of natural chemistry, too.
Being gracious about interpersonal differences without mistaking 'civility' for 'friendship' is a very cool thing.
