On another anecdote, similar to the OP story here - A good fried whom I used to play cricket with, had a sister, whose boyfriend was driving home one afternoon when a 3 year old boy chased a ball onto the road in front of his car, and was killed by the impact. He wasn't speeding or doing anything wrong. It was a pure accident. He was distraught about it and I believe, like the lady in the story, stopped driving for many years. I look back on the episode now and realise that I had no social cues as to how to approach him about it or offer him comfort in any way. I wonder how he is doing now - we lost touch and I have no idea where he is these days.
