do you hear that rumbling in the distance? Max does!
He gets excited and starts yelling "choo choo! choo choo!" even if he can't see the train.
What about that familiar mechanical sigh in front of the house?
that mysterious flying silver thing?
"barepane!" (it flies in the "ky," in front of the "mouin")
and, my personal favorite, when playing with his car-made-out-of-a-coconut (a most awesome souvenir from St. Lucia, thanks Grandpa!):
"moooom, mooom! beebeep!"
...be honest people you can't really say "vroom" either.
