One day, a little boy named Tim went to the library. It was a gloomy day outside. Tim felt sad because he wanted to play in the park. But he knew the library was a fun place too. Inside, he found many books with colorful pictures.
As Tim looked at the books, he met a girl named Sue. Sue said, "I like to spring and jump on gloomy days. It makes me happy." Tim thought it was a good idea. So they both started to spring and jump in the library.
Soon, the librarian came and said, "Please stop jumping. It is not safe in the library." Tim and Sue stopped and said sorry. They learned that it is important to follow rules and be safe. They sat down and read books together. The gloomy day became a happy day because they made a new friend and learned a lesson.
