My DH does the same thing, and MORE. He comingles everything and when he takes the clean laundry out, he frequently dumps it on the floor (somewhere, anywhere, everywhere in the house) for folding, and then walks away to do something else. Clean laundry doesn't belong on the floor. DH has many fine qualities, but laundry style is not among them. I hate it when he "helps" with the laundry.
