The scene: Kids building Legos. Brennan working on an semi-truck and Charlotte asking him a million questions.
Brennan: "Mom, isn't that right? You don't have to hold the steering wheel when you're driving at night and you need a nap or something?"
Me: "No way, you always have to hold the steering wheel. You don't ever sleep while driving."
Brennan: "Well why do semi-trucks have beds in the cab?"
Glad we got that one straightened out!
