Where vs. Why

So, I really thought the question was supposed to be "Why?"

Apparently, I was WRONG.
It's "Where?"

Where choo-choo train?
Where tracks go?
Where Daddy?
Where Ba?
Where Mr Craig's house?
Where bikes?
Where vaccumes?
Where our car?
Where Emily?
Where choo-choo train? (yes, again)

So on and so on..... that was only a very small fraction of our trip to Target this evening, many repeated many times.
ARGGGHHHH!!!!!!!!! :shocked:
I thought this was supposed to wait until 4 or 5 and then be "Why?"
