He can clean and polish he just can't tidy, ie. put his and my crap away!

Why is it I know where all his rubbish lives and can tidy it up but he doesn't know where mine lives. It's the same with putting away washing. When I do it I do mine and his. When he does it he claims not to know where any of mine lives.

You know where the knicker drawer is, can you not at least put those away!?!?
