One day, a little girl called Mary was playing in the sand. She saw a crab and said, "Hi crab!" But the crab didn't answer. Mary waved her hand, so the crab waved back. Mary was happy and started to play with the crab.
Suddenly, a jealous crab came along and said, "That's my friend! Leave him alone!" Mary answered, "I'm just saying hi and playing with him. I didn't do anything wrong!" The jealous crab didn't agree and started to fight with the other crab. 
Mary was scared and ran to the shore. She looked back and saw the crabs still fighting. She waved goodbye and ran home.
