burning a hole in his pocket

Simeon, on the phone with Francois after finding a whole dollar under his pillow:

Papa! The Tooth Fairy came! And when I woke up, the tooth was GONE. And there was a dollar bill there! I was thinking on Saturday? We could go buy something with it.

(Francois comments, "Sure. Or you could save it...")

[Pause.]

I'll save it until Saturday! Then we can buy something with it.
