We were discussing the Trinity over lunch today.  You know, one God in three persons?  Well, River always asks the best questions.  Always. :-)

M: Momma? I have two feet.  Does God have three feet?

Ellie's favorite question?  Why.

You don't realize how little you actually know until a child asks you "why?" or "how?"

What was it Einstein said?  "If you can't explain it simply, you don't know it well enough."
