This morning when I got up, I was very hungry. I went into the kitchen to make my breakfast. I went into the kitchen and….

“Help!” I cried. “Mice! They’re eating my breakfast!” I really don’t like any mice. However, I really hate mice that eat my breakfast!

I didn’t like the brown mouse and it was eating my bread. I disliked the balck mouse and it was eating my cheese. And I couldn’t stand(忍受) the white mouse and it’s eating my chicken feet! But nobody came to help me.

I closed the door of the kitchen and I phoned Jim. He is my friend and not afraid of mice.

He came and we went into the kitchen. “One, two, three…open!” he said. I quickly opened the door, but there were no mice. How terrible! The only things left were three carrots, half a cabbage, and two pieces of bread.
