As a mother who's lost a child, I see no problem with the much-
discussed "silly string incident".  If you haven't done so, please 
contact Compassionate Friends.  They'll verify that parents are often 
in a state of shock for weeks, perhaps month after such a death.  They 
can't become "grieving parents", appropriately sobbing, etc. right 
away.  My first comment after returning home from my son's Memorial 
Service was to ask the house-sitter "So-what did I miss on General 
Hospital today?"  The reality doesn't sink in for sometimes months.  So 
for people to say that Darlie wasn't acting appropriately at the 
gravesite is so wrong.  She was acting totally appropriately as a 
parent whose children died.
