After spending the entire week as a dog, you found that being a dog wasn't too bad. There was a lot you could get away with, the dog food tasted great! The best part was that you didn't have any specific schedule. You could get up whenever you wanted, you could get your mom to take you on a walk any time she wasn't too busy, and you even got to scare off an old school bully who was trying to egg your house while your mom was away yesterday. You feel that you're going to miss being a dog and wonder if you could ask your mom if she could arrange for you to become a dog once every year for a week of the summer. Your mom walks in the door and says "Kids, come in here! I have the reversal formula!" You and your sister rush into the room where your mom is. She had you put some clothes on (which felt kind of ridiculous considering you were both currently dogs, but then again you were about to revert to being humans so it made sense.) She puts the formula in your water bowels so you can have one last drink as a dog before you return to normal. Your sister was the first to take a drink. You watched as she slowly started losing fur, her tail disappeared, she gradually got up on two feet again and eventually she was back to being 100% human. You take one last look around the room and then drink up your own bowl of water.
