Once there was an inside mouse and an outside mouse. One day they both went on a trip. They traveled up, down, across, around, through, between, behind, over, and under, until they finally met in the middle. Hello! Are they old friends?Or new friends?Did they just meet today?Or do they visit every day?And what do you think might happen next to the inside mouse and the outside mouse?
