Sometimes the best course of action is to get the hell out of your current situation, it could be a job, a date, or a night out in a new part of town, whatever the circumstances, we all have our limits.
While it's never fun to be driven to the point of saying "screw this, I'm out," it can be cathartic to say adios to a bad situation, and even more cathartic to draw inspiration from the stories of other people.
I was at the first day of a job at a fiberglass place. I was working in a section unloading trailers.
There was an incident with a forklift that resulted in a broken hand. Then I got absolutely covered in fiberglass dust. They didn't provide masks and I could feel the grit on my teeth. Everyone acted as if this was normal and even said the forklift driver was one of their safest drivers.
