No, but when they are 12, a parent should be.
Yeah, true. But can you keep a twelve year old in the house if they want to leave the place? Maybe you can tie them on the bed? <img src="/ubbthreads/images/graemlins/evilgrin1.gif" alt="" />
It's very difficult to know what you must do with teenagers. I'm not defending that mother, she shouldn't be proud of being a grand mother of the kids of her kids.
I only can hope I do it ok when my son grows up to be a teenager.
