I think you're staring at the "key" to your salvation in your own words: his friends, and his hang out, at Trumbull Mall. Those are the things he holds dear. You can use those things to get him to get things done. Does he like to eat dinner? Sure, everyone does! Are you the one who cooks it for him, I bet you are? Food's a great motivator. When he comes home, mouths off at you, leaves a mess, then goes off to hang with his friends at the mall, who's the sucker? You're "enabling" him by allowing him that privilege. I would sit down and explain to him that you've thought about what things that you'de like to see him work on: one, is his cleaning up after himself, and another is his back-talking. And tell him calmly but matter-of-factly, that you love him and so this is why you are taking the lead in him making these changes. You will reward his helpfulness around the house with, say, cooking him dinner: which is probalby something he takes advantage of and for granted. If he's too busy to clean up, he can use that energy he didn't use for cleaning by cooking himself dinner, that's not your problem! Do you do his laundry? maybe he'd like to hang out at the mall in dirty laundry... or wash them himself? The more you do FOR a child who does nothing FOR you or himself, the more you're saying, not with words but with deeds, that what he's doing to you is acceptable. It IS NOT. Unless he's one of those kids that simply will not listen and will walk out of the house regardless of what you say, you can always tell him that until he's done the few things you've asked him to do, he will no longer be allowed to go to the mall, or go visit his friends, or whatever things he likes to do. Oh, I see you picked up your room, SURE you can go to the mall today! That sort of thing. Gosh, I was going to let you go to the mall, but I see the dishes are still in the sink. If you change your mind and decide to wash them, I'd be happy to let you go! Let him earn the things he likes BACK one by one as he does what's expected of him. I have an 18 year old son who's 6 foot 3, and a 17 year old who's 6 foot 1, so I know what you mean, it can get intimidating having someone that big looking down at you, and little you are trying to tell them what they're supposed to do! But my sons, thank God, they are well trained little runts and they tend to listen to what I say, I'm lucky I guess! But in their whole life I never tolerated that, so they just know better then to not listen to me. If they want to have any social life whatsoever they just do what they're told at this point! Good luck!
