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