Worked in a call center once connecting terminally Ill old people to nurses (a specialized aska nurse line essentially).
My job was just to call people who needed a call back and then hand them off to a nurse when they answered the phone. I’m talking like 15 seconds of phone time with these people on average.
The shit I heard in those 15 seconds was wild.
“Can’t talk, I’m on the other line with Jesus” was one of my favorite dark replies from a person with essentially terminal COPD.
But there were plenty of “I lived a bad life, I know why this is happening to me” type digressions.
