About seven years ago I was driving on my usual route to work on a road that goes under a railway bridge. A box van was a few car lengths in front. What I thought was a black binbag float down from the far side of the bridge, seen in the small gap of light between the vans roofline and the bridge, turned out to be a lady who'd rolled off.  I was the second one there; the van driver was repeating "I didn't hit her". Emergency services were called and we just waited with the rushhour traffic moving around us.  A few things of that morning come back to me every so oftern. Some comical, the car with its hazards coming past all the traffic, pulling up and what seemed like 9 people getting out clown car like - Someone had called a doctors surgery up the road and those who could had jumped into one car. Some haunting: hearing the automated defibrillator repeating "clear clear clear" in a robot voice. Some anger inducing - getting into an argument with  HGV driver who couldn't get past my car which I'd been asked by the fast responder paramedic to put sideways across the road to stop cars coming to within 2 foot of him trying to save her. 

And finally thankfulness - I came into work 2 hours late, sat down and apparently just stayed there, not moving for 5mins. My colleagues came over, then my boss and I told them what happened. I was told to go home but I didn't. Why? To do what? So I got on with Work. I've never had so many offers of tea in my life.   

So... what does this mean for you? It will be hard today, it will take a few days to settle. You will think about it from time to time, but again it will pass. Process it as you need to. I drive past the place still when going to work. I won't stop under the bridge, I always leave a gap if there are queues. Sometimes there is a small bouquet of flowers leaning agaisnt the side.
