I take great pleasure in overhearing my children's conversations. The best ones, like this one they had on the way home from karate lessons, happen in the car.
Evan: When I get tired of being an astronaut I have an idea for the best job!
Flynn: What is it?
Evan: I'm going to be a zoo keeper!
Flynn: Ooooh, yeah! I want to be a zoo keeper after I get tired of being a princess!
I love how they're planning ahead for their retirement at the ripe old ages of 6 and 4.
