I had different friend groups. In the neighborhood where I lived till I was 9, there were about six of us plus a couple of slightly older or younger siblings that sometimes tagged along. My next neighborhood didn't have many kids, but I hung out with one girl on my street and a pair of sisters from the next street over. I changed schools a lot, so I didn't have any close school friends but plenty of friendly acquaintances. But the ones that stuck were my theater friends. There was a pack of about 15-20 kids/teens/young adults that were in basically every show together for over a decade, and we did all kinds of stuff together in between shows. Most of us have moved away since then, but we're all still pretty tight. Three in particular I still count among my very closest friends.
