Eli: Mommy I want that sword from the junk store (antique place).
Me: Um no. If you want something you are going to have to work for it, plus you will stab me and/or the dog.
Eli: Mommy, you are good at massages. How much money would you charge?
Me: Say 20 minutes would equal 20 dollars?
Eli: Well then I would make 15 dollars and you would get 5.
Me: Why would I get 5 when I am doing all the work?
Eli: Mommy I came up with the idea, so the person who comes up with the idea makes all the money.
