William went to the shop.
He saw that there was no one there.
He went on his own.
He saw a robot had come, and the robot wanted to eat all the food.
William couldn’t buy anything, because he couldn’t spend any pennies at someone’s work because there wasn’t enough work, but he had a spare work and he could get up the stairs.
He saw there was some food.
Then the robot stole his food and ate it all up again.
Then William went home and worked on his computer to know that there was some food.
