he is driving me mad at the moment.
Apparently, we are poor because we don't have a certain type of cereal
, our house is not big enough (it is), he has nothing (he has the usual stuff), etc.
He had a 'Lynx' war this morning, used up his 2 cans of spray and I told him that he has to replace them. He shrugged. He will still be replacing them himself 
He has already lost the pocket money he has not yet earned this week for rudeness, but he still has to carry out the chores, etc, that he does to earn it. And we have only just decided last week that he could have a little pocket money
x 2.
He is almost 11, has always been argumentative. Is this it for the next 8 or so years?
Must admit I am dreading it. Does anyone have any effective tips? Am I being too harsh making him buy his spray back and carry out his chores? It was easier when they were babies
