When I was young I believed there was a robot who was trying to kill me. I stopped believing in Santa before I stopped believing in this. I found out the truth eventually. The robot was really trying to give me some crisps.
   I met a woman at a garden party and I told her about the robot. She spent the next ten minutes laughing at my stupidity, but I hadn't laughed at all when she told me about the sword of Damocles that was hanging by a narrow thread over her head. She believed that in between the sword and her head there was a cat. She hoped that the cat's reaction would warn her of the sword's descent and she'd have time to get out of the way.
   Her laugh came to a sudden end when she heard a cat screech. She dived into a nearby hedge. When she peeped out a few seconds later, everyone was looking at her. The cat who screeched had been asleep on the patio until the robot rolled over its tail. When she realised what had happened she would have appreciated a hole to hide in. But the robot is incapable of detecting embarrassment. He went over to her and offered her some crisps.
