I have no idea since we were always outside playing, or at the pool from sun up to sun down (unsupervised!).
I really don't know that we ever had these type of conversations with my parents. They both worked (a lot) and we were latch key kids and roamed the neighborhood looking for friends who had good snack food a their houses (like soda and chips) which we never had at home...
I am sure the other parents loved us
Plus we always needed rides to practices and games and movies, etc. my parents didn't ever want to drive us anywhere and we hated taking the metro (plus other parents thought we were too young to be doing it alone so we usually caught rides with friends.
