Why?

One can ask, "Why?" pretty much forever. You learn that once you have kids. Conversations between Elias and me go something like this:

Elias: Where is the fountain? (It is a fountain that is just a stream of water that sprays out of the ground)
Me: It's not on anymore.
Elias: Why?
Me: They turned it off for the winter.
Elias: Why?
Me: So the water wouldn't freeze in it and break it.
Elias: Why?
Me: So that it can be on again next year.
Elias: Why?
Me: Because people like to see the fountain.
Elias: Why?
Me: Because fountains are nice.
Elias: Why?
Me: I don't know.

This conversation repeats again the next day when we pass the place where the fountain used to run. A little tip for those of you visiting, the only real way to get out of these never-ending conversations is to say, "I don't know."
