It was a busy walk to work this morning. Further on - having evaded the hordes of undead - I was walking through a small wood and approaching the crest of a hill. As I walked up the slope it occurred to me that I had no idea what to do if a tiger was waiting just over the peak. I'm not paranoid or egotistical so I don't expect it's waiting there specifically for me, it's just standing there swishing its tail and passing the time. If you've had time to think about this then it hasn't attacked yet, which means you've got a chance to get out of this.
What do you do?
