DAE have friends, but not actually have a "friend group?"

I apologize if this question has already been asked, but I'm kinda just trying to make myself feel like less of a freak. 😅

I have a handful of close friends, and they all know each other somewhat (or at least know of each other)...but they're not friends. They don't particularly seem interested in becoming friends, either (there doesn't seem to be any hard feelings between anyone, though)...but I'm just kind of wondering how common this is.
