A conversation between me and my children while driving down the road:
Brendan: Mommy, did you know that they make a car that is also an airplane? Wouldn't that be cool?!
Me: Wow, that is pretty cool. I'll bet you'd need a special kind of license to drive one of those
Brendan: Yeah, how would that work?
Me: Well... you'd have to get a pilot's license in addition to a driver's license
Brendan: So, how would you get your pilot's license?
Me: You have to take lessons. And get lots of hours flying with an instructor.
Aubrey: Well where will we go?
Me: (pause) What do you mean where will you go?
Brendan: She means where will we go?
(Right... because asking the question a second time gives me total clarification...)
Me: (let's try this again)... um, I don't understand what you mean...
Aubrey: Where will we go while you take your flying lessons?
*long amused pause*
Me: Sweetheart, I will not be taking flying lessons
Brendan: (while Aubrey let's out a soft whine) Well I guess we won't be getting one of those airplane cars then...
