Why?

Maxx is getting to the "why?" stage.  Here is today's conversation when I picked him up from school and was getting him in the car.

Maxx: It not rainy.  Why?
Me: It's just not.
Maxx: But it wet out.  But d'ere not any rain.
Me: You're right.
Maxx: Why?
Me: Well, it was raining earlier, but it stopped.
Maxx: (pointing at a bird) Why the birds can fly but they not get wet?
Me: They have a special oil on their wings that helps the water slide right off.
Maxx: Why?
Me: So they don't get wet.
Maxx: Why we can walk but we no can fly?
Me: Because we don't have wings.
Maxx: Why?

At this point, he was all strapped in, so I shut his door and walked around to my side of car.  And that was the end of that conversation.
