—Yes, you can.

    One day Skygirl went to the library with her good friens, Spaceboy. She was very happy. She took a hamburger and a cola with her. She wanted to run, to hace some food and drink and to talk to Spaceboy. She was not happy when she saw the signs in the library. The sign on the left means "No running in the library." The sign in the middle means "You must not talk in the library." And the sign on the right says "Never eat or drink in the library." So she talked to the spaceboy quietly, "Let's go out. I am not happy here." They went out to the Supergarden. But they also saw some signs in the garden. One of the signs means "Don't climb the trees." Spaceboy was not happy because he liked climbing the trees. "We don't like rules, but we can go nowhere because there are rules round us."
