I'm generally social withdrawn, so my views are a bit skewed, that said I have no idea how people seriously think they have 20-100s of "friends." Like, maybe their personal definition of friend is just waaaaay to generous, because there's no way in hell they have time or energy to be involved with that many people on any decent level.

There are a near infinite of degrees of closeness relationships can have.

Friend of a friend I never hang out with solo but spend basically the entire night hanging out with once a year at a holiday party.

Old best friend who moved away and you've drifted apart but still stay connected with.

Guy I've played pool with almost once a week on and off for years but is kind of a dick and wouldn't do anything else with. New guy who's started playing pool and actually vibes and who's house you've been to a couple times. 

Friend you text all the time but moved to another city. 

Best friends SO you see all the time and sometimes get along with really well and other times you both grate on each other

Which of those are friends? Which are friendly acquaintances? Which are just people you know?

Some people only want to count what other people would call best friends as friends at all. Others might casually refer to all of them as friends
