Yeah, that's harsh. I was at a used bookstore and saw a man on a bicycle get hit by a utility truck, one with a cherry picker basket on the back. It actually ran over this guy's head and brains and blood splattered onto the wall of the bookstore within about two yards of where I was standing. That one still bothers me.
Aww man, I'm sorry to hear that. Hey...keep in mind, that's a trauma so treat yourself kindly over the next few days. Sorry for her family's loss but your experience will stay with you awhile.
