Non-american here! In the U.S, when you’re 21 you can access to certain things that you can’t do even if you’re over 18, right?
So considering that they all usually go to college together, how does that work? For example, a 20-year-old being friends or even dating a 21-year-old, they’re both adults, but one of them can access to things that the other one can’t.
Sorry if this is a dumb question!
