do you leave rubbish around the place? drop litter?

it makes me so MAD

i know it's my own fault for not trailing round the kids saying 'don't eat in here, don't drink in here...' but I can't be arsed and just think they should have the manners to put their rubbish in the bin they have to WALK PAST to leave the room...

grrrrgrrr...what shall I do?
