Mrs. Wen had two children, James and William. The boys were always fighting, both at home and at school.
One day, they fought again at school. Their teacher called Mrs. Wen and told her about it.
"Oh, I have had enough!" said Mrs. Wen after she put down the phone. "Why can't they help each other and stop fighting?"
When the boys came home that day, Mrs. Wen took some chopsticks from the kitchen.
"Try to break these," she told them. Neither of them could break the bundle. Then she gave them one chopstick each.
"Now try to break it," she said. They both broke their chopstick easily.
"You see," said Mrs. Wen, "We are like these chopsticks. We are only strong when we help each other."
After that, they never fought again.
