The guy on the right would turn around to face the wall and the the others would creep up on him slowly trying to gain ground without being seen. Suddenly the game seemed to stop and they all went to sit down right in the middle of the road. They were obviously aware of the exact time as the food delivery van came speeding round the corner. They had carefully positioned themselves between the wheels and would have been fine if I hadn't caused them to stand up and look at me by shouting "DUCK".
