Sara is a lovely girl who has long hair, and she likes pink clothes. But she has a very messy toy room. How messy? See with your own eyes.

In week one, Daddy asked Sara, “when are you going to clean up your toy room?” Sara said, “don’t worry Daddy, I will clean it up.”
In week two, Daddy asked Sara again, “when are you going to tidy up your toy room? It is so messy, no one wants to play in it.” Sara said, “when I have time, may be next week.”
In week three, the toy room remained messy. Daddy sighed.
Then, Daddy had a dream that night, and in the dream, the room remained messy for a very long time. One day, a little girl appeared in the toy room, she was wearing pink dress and she was cleaning the room. Daddy looked at the girl and asked, “who are you?” The girl answered, “I am Sara’s daughter. My Mum never got time to clean the room, so I came to clean the toy room.”
Daddy woke up, and the toy room looked like this.

A girl in pink cloth smiled and said, “I tidied up the toy room, Daddy”. Guess what, it was Sara.
