What's one of your biggest pet peeves?

One of mine is people who speak constantly during a movie. Who shout and argue with the characters, or ask everyone else what's going to happen when they're all watching the movie for the first time.

It's fine if you feel shocked, or affected by what's going on. I cry easily if I watch someone else cry, or in particularly emotional scenes. But I keep it to myself and try not to disturb everyone around me.
