sadness.

i got a call on thursday that started with:
"he's okay, but..."

those calls are never welcomed, rarely expected, and usually difficult to hear.
my dad went on:
"grandpa is in the hospital.  he had a stroke."

it was this time last year that grandpa cape's health started deteriorating so quickly.  this year it's grandpa forsman.  i pray it does not end so quickly.

how is it that sadness can affect us so deeply and so quickly?  where does it originate and why do i feel so much of it?  and then, how do you cope with it without forgetting about its source?
