Who can reason with the wunchie?

The other day Miranda and I were riding together in the truck. I'm not sure what prompted it, but she asked me "Daddy, why is my door locked?" I responed, "Honey, the door is locked because it always has to be locked when we're driving to keep us safe." She was quiet for a minute. Then she says, "Daddy, I don't think that you're telling the truth." I ask her, "Sweety, why are you saying that I'm not telling the truth?" She says, "Because of that," and points across the cab of the truck to my door which is unlocked. Busted.......I'm sure it won't be the last time....
