One day, a little boy named Tim went to play outside. He saw his shadow on the ground. Tim said "Hi!" to his shadow, but it did not say anything back. He thought his shadow was a new friend that was harmless. Tim and his shadow played all day. They played with a ball, they ran, and they jumped. Tim was very happy with his new friend. But then, something unexpected happened. The sun went away, and Tim's shadow disappeared. Tim was sad and thought his friend was gone. He went inside his house and told his mom. His mom said, "Don't worry, your shadow will come back when the sun comes out again." The next day, the sun came out, and Tim saw his shadow again. He was so happy and said, "Welcome back, friend!" Tim now knew that his shadow would always be there when the sun was shining.
