How am I supposed to tell if his boxers are dirty or not?

Well, I mean if he wore them already.

Trying to straighten up my bf's off campus apt at school this visit. But like he's such a disorganized person. He does laundry but he just throws the clean stuff anywhere, and he does the same thing with his underwear when he takes them off there are underwear and socks tossed everywhere. It's easy to tell the worn socks apart.

Anyway he's not here and gonna be gone for about an hr and a half.

I'm trying to sort the worn ones from the clean ones but I can't tell which are which.

Help.
