was in my room when I heard a plane in the sky. My little brother, Andrew, was at a friend's house. Mummy wasn't in the room. Seth was at work. (Seth is my stepfather.)

Usually I don't look at planes. But soon I will fly to Nebraska to visit Granny and Grandad. (They are Seth's mother and father. They live on a farm.) "Hey, plane!" I called. "Soon I will ride on you!" I went to my bed. A suitcase1 was on the bed. "Goosie," I said to my toy cat, "I will bring you to Nebraska with me. But I will not pack2 you now."3

Goosie didn't answer. But I talked to him. I am Karen Brewer. I am seven years old. My brother is four. We both have blond hair and blue eyes. I like real animals and toy animals. You can talk to them. They cannot answer but you can think that they can talk.

"Goosie," I said, "I hope you are not afraid of flying to Nebraska ... I am not afraid. Once I went to the camp. Kristy and her friends were there." (Kristy is my big stepsister.) "But now I will stay with Granny and Grandad."

I looked at my suitcase.

"Oh, I forgot my roller skates!" I put my skates. Then I put five books and my doll. I wanted to close the suitcase. But I could not do it.

"Do you want my help, Karen?" asked Mummy. (after Ann M. Martin)
