Actual conversation with The Princess in the car today:
The Princess: Daddy, do you know what I’m going to be when I grow up?
Hubby: I don’t know, tell me.
The Princess: A battery changing girl – do you guys know what that is?
Me/Hubby: No, can you tell us?
The Princess: It’s who goes around and if something needs a new battery, I put it in.
Hm. That won’t much help her support Hubby and I when we’re old and gray.
