That is a very odd post. Reads like a romance novel and then turns gross.
Of course...I worked in healthcare for 50 years, and my wife was a critical care nurse, so I was not in the least offended by these people mugging it up with urine samples.
It was a very stressful career and often sad, and humor is one way people deal with it. I used to go to Christmas parties and would listen to the bawdy, raunchy, hilarious stories told by all the nurses my wife worked with, and they poked fun at things that would probably offend some people who didn’t understand it.
I understood it all very well.
I have made it a point over the years to reach out and acknowledge and speak to veterans, many of them combat veterans, and the stories they tell about being at war are fascinating, yet both sad, and...funny.
I notice that they very much enjoy the funny ones, and when you listen to them out of the context of whatever immediate context they were in, they sound almost macabre, and you sometimes wonder how people find humor in those kinds of things.
Yet, they do.
I suspect that police and firefighters also are quite interesting to listen to at their “closed” parties where they laugh at certain things when non-police/firefighters are not around.
I think it is a coping mechanism, I think I get it...:)
