Why?

Markie's favorite word is "Why?"  A conversation yesterday went like this:

Mark:  What is she doing?
Bri:  Stretching.
Mark:  Why?
Bri: Because she's gonna go running.
Mark:  Why?
Bri:  She just wants to exercise.
Mark:  Why?
Bri: So she can be healthy.
Mark:  Why?
Bri:  Because.
(VERY slight pause)
Mark:  What is she doing?
Bri:  Stretching, silly.
Mark:  Why?
Bri:  Because.
(another small pause)
Mark:  What is she doing?
Bri:  Stretching.
Mark:  Why?

This is just one example of the types of conversations you can have with a three-year-old named Marcus.  Our kids get annoyed.  I just think it's funny.
