What's the one thing that sticks in your mind that a parent said before going out on a date?

@SageWanderer My parents just told me hell awaits those that have sexual relations outside marriage almost messed up my teen years!

@traceavery My parents were realists. They knew what could happen so my dad handed me a condom and said, "Your too young to be a father, and we're too young to be grandparents". So if it happens use it!
