Once upon a time, there was a wealthy man named Tom. He had a big house and many toys. One day, Tom found a long string in his room. He was very happy and started to think about what he could do with the string.
Tom decided to raise the string up and down like a game. He tied one end of the string to a toy car and the other end to his window. When he pulled the string, the toy car went up. When he let the string go, the toy car went down. Tom played with the string and the toy car all day long.
But then, something unexpected happened. As Tom was playing with the string, he saw a little bird outside his window. The bird was trying to fly but could not. The bird's wing was stuck in the string! Tom quickly helped the bird and let it go. The bird was so happy that it gave Tom a big hug. From that day on, Tom and the bird became best friends, and they played together every day.
