She said "It's President's Day!"
(She is a smart kid.)
I asked "What does President's Day mean?"
I was waiting for something about Washington or Lincoln .... etc.
She replied, "President's Day is when President Obama steps out
of the White House, and if he sees his shadow we have
one more year of unemployment."
