    It was a summer evening.  Rose was in the yard watching the stars with her family. Rose felt bored because all the stars were the same. As the whole family looked at the sky, Rose looked at the ground.She saw a lovely cat sitting beside her feet.  Then she gave him something to eat and called him Frank.

    That summer, Rose fed Frank every day.  But she couldn't make the decision to take him into her house.  Frank just came at about six o'clock every evening.  Rose would feed him whatever she could find.  She didn't know where he went after meals, but she knew he would always come back the next day.

Though the weather changed, their routine didn't change.  Then winter came.  In the first cold month, Frank came five times a week. During the next month, he only came every three days. By the end of the year, Rose hadn't seen Frank for two weeks.  Rose was very worried. She told her mother about it.  "Don't worry, honey," said her mum.  "I think Frank will appear again when it warms up,And when he comes, I think you can invite him to move inside." "Really? Thank you, Mum!" Rose said happily.  She was so eager to see her friend again.
