I didn't go out much, so it was determined on a case by case basis.
11:00 normally if just hanging with friends at the coffee shop. If I was going to see a 9:30 movie, then home was whenever the movie got over.
I didnt have strict rules apply to me growing up because I was a good kid.
I also didn't really drive much until I was in college because I didn't have my own car by then. I hung out with a bunch of guys all the time, so they always drove their cars.
