I commented a few days ago how I had waited an hour and ten minutes for the police to come whilst our vehicle was under attack. This was in fact the second assault we had undergone in a 7 day period and I was pretty weary of being scared. The decision to go to work the next day was not an easy one, and I turned up with my head hung low, my feet scuffing the floor and wondering why I was doing this anyway. That was the point at which I found the card in my tray from a patient we'd treated several weeks earlier who I thought could just as easily have gone on to die as to survive. Not only was she very much alive, but she was also very grateful. That thank you card got me back in the van again and got me back on the road. They are worth so much more than the authors will ever realise.
