Why did the little boy ask why and then why again?

Avi wants to know the "why" of just about everything these days.

Avi, my three-year-old grandson, has recently launched into the "Why" stage of life. So he's wondering now why the sky is blue and water wet, why the sun is hot and ice is cold.

Curiosity is a good thing, but when every explanation is met with a question it all can be a little, er, annoying. Fortunately, the why of life can also be funny.

Here's a mostly true conversation Avi and I had just the other day:

Avi: What happened to your hair, Pops?
Pops: It fell out.
Avi: Why?
Pops: Because I got old..
Avi: Why?
Pops: Because I wanted to stick around so I could play with you.
Avi: Why?
Pops: Because you're so darn cute.
Avi: Okay ... gimme a cookie.
Pops: Why?
