This morning my 14 year old was asked to lock the back door before we left, he came out of the house and said that he'd done it so I asked if he was sure - he snapped that I didn't need to check and he'd done it.
I've just got home and the door is unlocked, I'm thinking of saying he can't use the laptop, mobile and TV for 24 hours to give him an idea of what it'd be like if somebody had come in and stolen them.
AIBU?
