A teenager, really? Nothing he'd mind if you saw? Nothing YOU'D mind if you saw?
There are some things that most all perfectly normal teens do... alone... with the door closed... that I'm pretty sure they don't want mom or dad walking in on and that no one wants to walk in on. Did no one learn anything from George Costanza?![]()

Of course my kids can be in their rooms with the door closed. I honestly can't believe that some parents don't allow that without a valid reason ie: drug use, smoking. I remember being a teen and my room was my refuge. I used to just love to lie on the floor and listen to music and read. As for knocking, I do that too and wait for a response before entering. Otherwise what's the point of knocking?
