Our son will not complete any chore he asked to do. He will start a chore, (cleaning fish tanks and cleaning horse stalls) after being told many times but he doesn't complete it thoroughly after being told over and over how to do it. He just doesn't seem to care about anything and no consequence effects him. He just say's "my bad". He has destroyed several tools, even a John Deere Gator we use on the farm because he so rough with it and hasn't taken care of it. We've made it off limits but will catch him riding it without permission. We've already taken away electronics and cancelled all outside activities (except his team sport) and he doesn't seem to care.
