I know, kinda weird question. Son shaves with cordless razor in bedroom, while walking around. Should I be concerned about the hair falling on the carpet and other furniture?

It's kind of gross. Hope he is the one who vacuums.

Do his future wife a favor and get him to shave at the sink and then clean up.

You may just have to deal with this on principle and not argue about how much facial hair is added to the carpet.

We don't clip our fingernails in the house, and if you drop food on the floor, we don't leave it there if the dog doesn't get to it first.

Tell him you don't mind him walking around and shaving as long as he does both outside---and brushes off his shirt before he comes back into the house.

It may not seem like much hair to him, but to me, that is kind of gross. For comparison, have him stand at the sink to shave and then tell him that all of this hair is now all over the house, thanks to him not standing still to shave over the sink. Hand him the vacuum and the dust rag so he can clean up after himself when he's done wandering around shaving.
