Once upon a time, there was a dependable dog named Spot. Spot loved to play with his sheet. He would run and jump and fetch the sheet all day long. Spot's best friend was a little boy named Tim. Tim and Spot played together every day.
One day, Spot and Tim were playing with the sheet in the park. A big, mean dog came up and wanted to play too. The big dog said, "Give me the sheet!" He was very demanding. Spot didn't want to give up his sheet, but the big dog was very big and scary.
Spot tried to be brave and said, "No, this is my sheet!" But the big dog didn't listen. He took the sheet from Spot and ran away. Spot and Tim were very sad. They went home without their sheet and never saw it again.
