If the appropriate linen bin is upstairs, in that.
If DP hasn't brought it back again after doing the last load, everything goes on the floor until it does, as I'm not risking white and lights in the colours bin with his propensity for picking everything up and ramming it into the machine without checking.
And if it's knitwear, it goes down the side of the bed until Saturday when I wash my own woolly stuff, as I certainly don't trust him with those after a decade of bitter experience.
