I’m torn. My room was searched (more or less) quite frequently and I ended up being in trouble for various things found there. What irritated me about it was that it was a violation of trust. I had given no reason for the searches, I was a great student, I came home when I was told to, and so on.
But, not to be silly, the reason I didn’t like the searches was because the parents would find something I didn’t want them to, and not because of a matter of privacy but because I knew I would be in trouble for it.
So, torn.
If I had a child I would be very nosy. However, I would tend to fall on the side of thinking of it like a sneak and peak warrant: I couldn’t use anything I found to directly punish the child, only as a means to better understand what was going on with her (always wanted a daughter).
Some teens are simply distant from their parents, they are reaching an age when they want to assert themselves like they damn well should and like we want to teach them to do. It is unforntuate that this often involves at least a temporary break in the parent-child relationship.
If you feel you can’t trust your child to tell you the truth, perhaps it is the way to go if you suspect something may be amiss. Better to have a child be spiteful and safe than otherwise, I think.
It is never fair.
