One of my kids (12) whines and pitches a fit at every.single.thing he's asked to do. Never does his chores on his own, and when asked it's like fingernails on a chalkboard and always ends up feeling not worth the effort. Last night we had a heated back and forth about feeding the cat, something that takes 60 seconds but was argued over for 15 minutes. It ruined my evening. Now he has a friend coming over this afternoon and I said I'm not going to clean up or buy snacks, that if he can't be bothered to contribute, neither will I.
Is this reasonable?
