This is a good as when I forced my parents into letting me buy a Nintendo. They had this system by which, we could read books and do a book report and earn cash for doing it. I read so much and did so many reports they owed me close to 250.00. My mom insisted that there would be no nintendo ever.
I told them, you can buy me the Nintendo Super System for my birthday and write off the whole debt, or when you eventually pay me off, I'll buy it myself. . .
I got it for my birthday.
EDIT: Just found out that Grandma already bought her the nintendo DS. That's enough gaming systems for a birthday. I am however going to pick her up some games, and books, and pudding. . .
