The Final Answer to Why

We're outside of the grocery store.

Me: Look! There's a butterfly...oops it flew away.

Buttons: Why do butterflies fly?

Me: Well, I think they like to fly and they have things they need to do like find food.

(2 minutes pass)

Buttons: Why do they fly, Mama?

Me: I think it's fun to fly. Wouldn't you like to fly if you could?

Buttons: Oh yes.

(5 minutes pass as we wait in line to return some spices)

Buttons: Mama, why do the butterflies fly?

Me: Why do you think they fly Buttons?

Buttons (scrunching face in thought): I have ta look it up on web-site.
