What should I do if I am sitting next to a stranger in a theater, and he falls asleep and starts snoring? 

When I was young and bashful, I would cough or make some other small commotion to try to wake snoring people. Now, I’m more sympathetic with sleepers and also more direct. I tap them on the shoulder and whisper: “You’re snoring.” No hard feelings! Sometimes it’s hard to stay awake, but that doesn’t give others the right to interrupt our experience.
