X-man always amazes me, I know I've said this before but he does, he's about 30 months old now and his grasp of English is growing daily.
He was sitting at the kitchen table the other day and we had the following conversation:
*sound of airplane going by*
X: *ponders* What's that? Oh, airplane.
D: That's right, an airplane.
X: *pause* No, a rocket ship.
D: You think it's a rocket ship instead?
X: Yes
D: Where do you think it's going? To another planet?
X: Planet?
D: Right, like Mars or the Moon.
X: Rocket ship to the Moon!
D: *trying not to laugh* That's great! Would you like to go on a rocket ship to the moon some day?
X: (exuberantly) Yes!
D: I'm sure you will some day buddy.
