I have two sons,10 and almost 13, and of course I love them more than life. But they make me crazy! I know it is our own fault that they don't do anything in the house. But there are things I could explode about: almost everytime they pour themselves something to drink they something of the drink, either while pouring or when carrying the full glass away. Of course they never clean up the mess. I'm not even that mad about them not tidying up after themselves but the fact that they still spill stuff! It is not that they are that clumsy (these boys are highly talented soccer players with excellent fine motor skills) they just don't care. I have shouted, I have explained, I have begged....it doesn't stop. If I ask who it was both deny. I know we have completely spoiled them (at least they are friendly, polite kids who know how to behave and I am glad they are but at home I guess we have failed.) but how could I start getting them out of this (as a starting point for all the other things that have to be done)? Provide them with some beakers?
