Tht's it really.
Ds (12) had a friend over last night. I cooked for him, cleared up after him, made his bed, let him have a lie in. I woke them up at 11.30, he got up, ate a bowl of cereal then just pissed off without a word (I was cleaning upstairs). He did however go out into the garden to say goodbye to my other dc, but no goodbye or thank you to me.
Is this normal? Bad manners piss me off.
