No wonder Penny wished for a world without adults. Her parents gave her the most unfair punishment. Sure, she lied about going to a night club, but being made into a personal servant IN YOUR OWN HOME is just too much for me to take in!
And to add insult to injury, no one was on her side, not even her mother. I tell you, if I was Penny, I would have done the following:
1) Wished for an adult-free world
2) Ran away from home
3) Reported my parents to the police
