Addendum

We are in the middle of math as I write.

Mark is learning about units of measure.  I was showing him milliliters and liters.  He said, "I've got news for you Mom, we won the war." 

He was quoting Corner Gas, the best thing to come out of Canada since ketchup potato chips. (Never mind.  Ketchup potato chips are nasty).

Mark is like his brother and sister and remembers funny lines from TV shows and movies with perfect clarity.  I wish I could translate that into them remembering other things with perfect clarity.  But I am glad that my children are armed with wit.  They bring out the big guns when they know I need to smile.
