Ever since I read that happily married parents tend to be stricter parents, I've been polling all my friends about what their high school curfews were. From my very unscientific research, most everyone had a curfew of 11 p.m. or midnight once they got their driver's licenses, though lots of my friends were completely curfew-less by age 18. How about you? What was your curfew growing up? When did you no longer have a curfew? And what curfew would you give your teenager?
