My unspoken personal policy is that if it's not in a laundry hamper or laying on top of the washing machine (as my husband likes to do from time to do), it doesn't get washed. I don't say anything. He eventually gets the message when he can't find something he wants to wear and either puts them in the hamper or washes them himself. It's worked for 43 years. I refuse to stress out over small stuff and this definitely qualifies as small stuff to me.
