My dad use to say, "don't let me catch you doing ..." So, he never did, but it wasn't because I didn't do it. He probably thought that I was a "good kid" at the time, but I was just smart enough to never get caught.
Jennyrae, you are right. We don't know you or your kid, and both your kids and their friends may be super nice people. I think too many people have heard stories about people's mature-for-21 year old kids renting a place and destroying more than a home. I always thought that it was a little wierd that you could join the military and kill people when you were 18, could drink when you were 21, get married and have a baby -- I am not sure if there is a minimum age, yet to rent a house or motel room, you had to be 25.
Did you see the interview of the mother of the young girl who recently robbed the bank in Atlanta (I think) while wearing sunglasses as her disguise? The mom said, not my daughter. She is a good and responsible young girl. I think many rental home owners hear many people say that, yet also hear horror stories by people who rented to them.
I like to think that I grew out of the silliness that I was into when I was young and foolish, but I was not the kid my parents thought I was when I was not around them.
Jennyrae, I don't think people mean you ill will on here. Their homes are somewhat like toothbrushes, and they don't let just anyone use them. ;-)
