To Coke;
( People like you are the “real thing” L.O.L. – you’re prob too young to get my pun)
In any case, it may be hard to ask the Mrs. you are helping to pre-sort.
But here’s a soloution.
Any time you come across a piece of laundry you dont care to handle, put it aside. then when you’re done you’ll simply have a very little (small) pile, which any normal Mrs. would understand. PS. It is perfectly logical as to why you wouldn’t want to handle the Mr. personal laundry. Duh! He’s not your father.
