Your children can be a pain in the rs at times with back Chatting, stubborn, trying to be clever if their mates are around, what form of correction do you use?
And, as Ummmm says, seeing the punishment through is a must. Back in '94, my then 14 y.o. daughter stole 6 cigarettes off me. I told her that each ciggy would cost her a week's pocket money - £5, at the time. Despite the protestations of my then partner, i stuck to my guns and those cigs were the most expensive she will ever buy. And she never stole from me again - to my knowledge, at least.
Haven't had that dilemma TWR. If I had, I'd have a word one to one about being respectful and how disappointed I were in them. If they crossed that line again, I'd tell them to stay away until they learned respect.
Agree Eleena, when mine were young all the shouting in the world was water off a duck's back, but if I just quietly told them I was really disappointed in them, it always made them a bit tearful and sad and seemed to have the right result.
