Did you have to cut off your then minor friends from elem to high school before you were 20?

I don't know how Common it is in the United states, but where I'm from in my country 18 is considered an adult, the age of majority like the usa and it's culturally expected that the moment before you turn 20 years old that you should have already cut off ties with anyone below the legal threshold of adults. I've seen 18 or 19 year olds play ball with elementary schoolers and middle schoolers but then as soon as they turn 20 they're expected to only have friends 18 or older. There were neighborhood kids in my old neighborhood that were like 10 or 11 to 16, my parents at the time knew their parents and I played video games and ball with them but stopped as I turned 20 cause that would be seen as amward.
