I'm Jack. I am tidy.

In my room, the books are always in the bookcase. My computer game is always there, too. My shoes are under the bed. My schoolbag is always on the sofa.

Eric is my brother. Look at his room. It's in amessnow. The books are everywhere—on the bed, on the sofa and under the desk. Where's his hat?

Is it on the bed? Is it on the chair? No. I don't know.
