Once upon a time, there was a little girl named Sue. Sue had a friend named Tim. They liked to play together. One day, Sue and Tim went to the park. They saw a big slide and felt the urge to play on it.
Sue said, "Tim, do you remember the last time we played on the slide?" Tim nodded and smiled. They both climbed up the slide and slid down, laughing and having fun.
After a while, Sue saw a boy named Sam. Sam was sitting alone and looked sad. Sue felt ashamed that they did not invite Sam to play with them. She said to Tim, "Let's ask Sam to play with us!" Tim agreed, and they all played together on the slide, becoming good friends.
