I do mine - I do our two DS's. He had a huge go at me this morning saying that YET AGAIN I had folded a dirty t-shirt of his back into one of his drawers. YET AGAIN I told him that if he just drops it on the floor I will put it away, I do not have time to individually check each item for dirt!
PUT IT ON THE LANDING SO I KNOW IT IS DIRTY! Or better still make your way down the one flight of stairs to the laundry basket and put it in there! Not ON it - IN IT!
Grrrr
