It's nice to do someone's laundry for them.
Will's roommate Chad is out for the weekend and forgot to run a load of wash he left in the washing machine.
Will wants to do his own laundry.
Will runs the washer with Chad's clothes, dries them, and hangs them up.
Will takes Chad's laundry out and puts it on the floor of his bedroom, then loads the washing machine with his clothes.
Chad thanks Will multiple times for his kindness and offers to get him dinner for helping him out.
Chad doesn't see the clothes when he comes home, trips, and is frustrated with Will for just leaving them there.
