"What's all the commotion about," says Dad as he steps outside. You would answer but you are surprised to see him naked and wearing a dog collar.
Mom leans over to your dad's ear and whispers, "He says he doesn't want to be the family pet."
Dad says, "Of course you do son. You'll enjoy it like I did."
You ask, "Dad, why are you naked?"
Dad says, "Someone has to teach you how to be a pet. The magic helps with some things like making you able to run on all fours and making you look like a dog to anyone who doesn't know the magic spell but since your mind is immune to magic, I have to teach you how to behave. So we agreed to turn me into a family pet for a while too."
You yell, "You're all in on this? Why would you do this to me?"
Dad says, "Do you think we'd agree to this if it was bad for you? I loved it when your Mom first turned me into her pet twenty years ago. We were already thinking about getting married but spending time as her pet made me certain I wanted to spend the rest of my life with her. You're getting old enough that we'll soon find an owner for you too."
Kat says, "I thought I'd get to keep him."
Mom says, "That would be inappropriate. Dan needs to grow up and get a life of his own. This family pet plan is temporary."
Dad says, "But I'm sure our boy will enjoy it so much he'll want to find someone to permanently be a pet too."
