She's also four years old, which makes these negotiations more than a little entertaining.
For example, today:
Genevieve: I would like a television in my room.
Me: You can have one when you're 20.
Genevieve: How about when I'm 80?
Me: OK. I will put it on the list for your 80th birthday.
Genevieve: I would also like a remote control, and I would like you to make me a Cinderella dress, glass shoes, and a crown.
Me: I will put all of those on your 80th birthday list.
... And maybe a princess cake, too.
