A while back, a couple of months before he turned 13, a day or two after he'd taken one of his occasional trips over your lap, he came to you to discuss the idea that he's too old for spankings.
"None of my friends get spanked anymore, Dad," he explained. "Couldn't you put me over the side of my bed for the belt, or paddle me like they do in school?"
You have no real objection to the idea, so you discuss it with a couple of your friends with older kids, and you try a couple of things, and come up with a solution that suits you both - you're sure you're still making an impression on him, when he needs it, and he feels like he's not being treated like a little boy anymore. The one caveat is that you mention - almost jokingly - that you reserve the right to put him back over your lap, if you feel he's acting too immature.
The past few days, Mark has been making you insane. You're planning to sell your house and move, and there are appointments to show the house coming in the next few days. Besides that, it's also getting close to the holidays, and you have plans to have a number of guests, including allowing Mark to have guests over. You've explained to him everything that's going on, told him exactly what needs to be done, and he's almost ignored you. You've given him a list to help him organize. Finally you give him an ultimatum.
Thirty minutes after delivering the ultimatum, you walk into his room to find this
You think to yourself that that might be an acceptable excuse, if any work had been done at all. When you push, he can't even tell you what he's done.
Is it time for drastic measures? What approach are you going to take?
