career changes

Our conversation while driving home from the store today:

Green Pea: I want to be a money loaner when I grow up.
M.E.: Ok.
Green Pea: What do you do if you're a money loaner?
M.E.: Well, you have money to invest and people who want to start a business or something come and tell you about their business plan and you try to decide who has a good plan and can grow their business and pay back the money.
Green Pea: I want to be a teacher and a pizza maker and then I'll try to be president.
M.E.: Oh, really?
Green Pea: Yeah, I'll be a teacher when I first move out of the house and get my own house and then after that I'll be a pizza maker and then I'll try to run for president.
M.E.: Where does being a money loaner figure into all that? I thought you wanted to be a money loaner.
Green Pea: (dismissively) Oh, I'll do that when I'm a teenager!
