A tiger has escaped from the city zoo. You know this because you live not far outside the city in a nice house at the end of a residential street and there is a tiger staring at you through glass door of your walk out to the deck in your backyard. He looks kind of peaceful, just sitting there, hardly moving at all but for the twitch at the tip of his tail. But you’re afraid to move in case that makes him decide to move. It’s much nicer just having a quiet, slow staring contest with the tiger. You just know things are not going to go all that well for you once he starts moving. How long can you keep up just staring and what finally happens to break the stand off?
