Conversation between three children in the play house:

Child #1 said, “I want the windows closed!”

Child #2 said, “I want the windows open!”

One child pushed the window hard and the other child pulled the window hard.

Teacher said, “I see you want them closed and you want them open. What should we do?”

Child #3 said, “It is simple, girls! Keep one window open and the other one closed.”
