I once went to a 999 call, single crewed, middle of nowhere. All I had over the radio was "screaming female". I was convinced it would be a domestic.
I turned up, to a totally inconsolable woman in a massive country house, who couldn't speak and just pointed to the stairs. I gingerly went up there, wondering what I would find, and it stank of burnt pork. Her husband had somehow bypassed any form of trip, and had wired himself up to the mains (via a timer) to electrocute himself. (He used the timer, to record his actions on a strategically placed camcorder, to absolve his wife of any accusation of wrongdoing). He was obviously cooked by the time I got there.
I spent the rest of my shift trying to console his widow, and completing paperwork for the coroner, whilst at their house.
By the time I had left, I'd been with the wife for hours and had built up a brilliant rapport with her.
I called a friend of hers to come and sit with her before I left, and as I was about to get back in the panda, I innocently said to her "Have you got any burning questions"

Thank god, she actually laughed a bit. I went to check on her a couple of times in the coming weeks when I had jobs in the area, and it never did affect our rapport!
