You're on an elevator with three other people. One of them passes gas. The elevator stops and those three people get off leaving you alone with the reekness. With only three floors left to go you figure you can tough it out. But then the elevator stops at the next floor. Two young children and an adult step inside. Immediately the kids react and one of them asks, "What that stinky smell?" The adult gives you a hard look.
Do you say anything? If so, what?
