You stand aside to let your double pass.
'I don't know,' grumbles the doppleganger, 'some people...'
When your double has gone a reasonable distance, you decide to follow hoping to find out where this strange yet familiar person is in such a hurry to get to. The double wanders through a maze of narrow passages which are new to you, but which your double seems to be quite familiar with. Unfortunately the doppleganger notices that you are in pursuit, and manages to lose you in the twisting labyrinth. This puts you in a foul mood. You wander fruitlessly through the maze exploring every passageway until finally you arrive back at the doorway you started out from. Here you find the doppleganger, standing on the other side and staring at you as though you were some kind of art exhibit. By now you are really annoyed.
'Are you going to get out of my way,' you snap, 'or do I have to punch you in the nose?'
