A bit late to the thread but here goes. Not so much someone’s last words but I think this is a reasonable thread to tell this story. 

I do a lot of work at an emergency department in a pretty deprived part of the UK. We say a lot of homelessness as well as alcoholism and drug addiction. The paramedics bring in this guy in his late 50s who had been found unresponsive in a KFC bathroom - he’d had a cardiac arrest, they’d tried resuscitating him en route and we tried some more when he got to us but sadly he didn’t make it. He was alone, and had been found in a not so nice part of what is already a pretty grim town, so the assumption was he was homeless/possibly alcoholic. None of this mattered whilst we were trying to resuscitate him but now he was dead, we figured it would be near impossible to find a next of kin (if he even had one). 

Turns out we were wrong. He was happily married with 2 adult children. He had been out shopping with his wife, needed the bathroom so went in to the closest place he found (KFC) but left her to carry on shopping. When she didn’t hear from him and he wouldn’t answer his phone, she must’ve gone into KFC and been told someone had been taken to hospital. I will never in my life forget her piercing scream when I told her he had died. It was the most heart breaking thing I’ve ever come across, as you could tell she hadn’t even registered it as a possibility. Don’t get me wrong, no one death is more tragic than another, but to go from being out shopping with your spouse to finding out their dead within the space of a few hours must be horrible.
