Here is some excellent advice. It’s good anytime you are sharing housing whether as a resident or as a house guest.
I read them on a tile in a wonderful house in Western Massachusetts. I gather from a little Web exploration that there are other versions. This one seems very good to me.
If you open it, close it.
If you turn it on, turn it off.
If you borrow it, return it.
If you don’t know how to use it, leave it alone.
If you break it, fix it.
If you can’t fix it, report it.
If you make a mess, clean it up.
If you move it, put it back.
If it doesn’t concern you, keep it that way.
