Dear People of Earth,

If you happen to see someone walking deliberately towards a restroom, or a room with a restroom in it, or with their hand on the door to a restroom, in the process of pushing it open, it is a safe bet that person is in fact going to the restroom. As such, you should refrain from trying to enter into conversation with that person. Otherwise you risk making that person poop/pee/vomit/change a tampon right there in front of you. And that's no fun for anyone involved.

Much thanks,
