Once upon a time, there was a little infant named Tim. Tim had a big sister named Sue. Sue and Tim liked to play together every day. They played with their toys, ran in the park, and laughed a lot.
One day, Sue went to her friend's house to play. Tim stayed home with mom. Tim missed Sue a lot. He felt sad and did not want to play with his toys alone. Mom saw that Tim was sad and gave him a sour apple to eat. Tim made a funny face when he tasted the sour apple.
Soon, Sue came back home. Tim was so happy to see her. They played together again and Tim forgot about the sour apple. Sue and Tim knew that they were the best of friends and they never wanted to miss each other again.
