Advice | Miss Manners: Guests keep dropping hair on my carpet

Dear Miss Manners: Some of my (grown-up) family members will pluck loose hairs off their shoulders and clothes, then drop them onto my carpet, without even trying to hide it!

I don’t say anything, but I wonder if I may ask them to put these loose hairs in the garbage can or compost container. I’m pretty grossed out by their behavior. Your thoughts?
