I remember when I was a young kid, I sat in a movie theater watching That's Entertainment with my friend and her family. Bored, I fiddled with my candy, and after unwrapping one too many pieces, my irritated friend's mom snatched it all away from me. Silence was restored. But with adults who don't know each other, restoring silence in a theater can take an ugly turn. Such as it did last week, when a man trying to enjoy the symphony in Malmo, Sweden couldn't take the sounds of his neighbor's scrunching gum bag any longer. The man grabbed the stranger's bag of gum and threw it to the ground.
