You check the bite marks on your shoulder. That squirrel might have had rabies or something like that. You think you should go to the doctor first thing tomorrow.
You walk home. You're right outside your house when everything gets strange.
Your head starts spinning and you feel an unbearable pain. You lay down on the grass and close your eyes.
Several hours later, you open your eyes to find everything looking pretty normal. You're actually feeling pretty good again. You stand up and start walking back to the house.
This is where it becomes strange.
The house is huge and you can't possibly open the large door. You sit down and think that you might have shrunk somehow.
You look down ...
"How did I turn into a squirrel???" you say to yourself, but it comes out as a squeak.
You don't know what is going on, but the sun is going down and you have to find a way inside.
