You get to take their pictures before they head off to the homecoming dance. You get to tell them that they can't leave the house until they clean their room. You get to hear about the teenage drama at school: which girl is "the one" this week, and who else likes her, and how she'd be perfect, etc. You get to remind them OFTEN to shut off the lights before they leave, to pick up their underwear from the bathroom floor, that six towels on their floor of their room is TOO many. You get to watch them play with your children, even if it adds lots of decibels to the room. In all, it's pretty entertaining.
