Sam was playing with Buster, his pet terrier, in the backyard. Taylor called and asked if he could come over.
"Sure!" Sam told his friend. "I'll be in the backyard. Just come through the side gate."
Sam heard Taylor coming down the walkway. Taylor hurried up to the gate, swung it open, and entered the backyard. He closed the gate behind him.
The two friends greeted each other. Then they began to play with Buster. What a shock they had when a third boy jumped the fence into Sam's backyard!
Buster barked. Taylor looked at Sam. Sam put his fists on his hips and said, "Hey! What are you doing?"
