Paramedic friend

You and David Shu have worked together for a while. You have never seen him buckle under pressure but you know he takes losing a patient hard. The ambulance made it to the hospital, but the patient didn't make it. You just finished restocking your supplies when you find David sitting in the back of the ambulance. (Hopefully the voice isn't too bad. I tried, but the voice isn't playing for some reason. Anyway, have fun!)
