Quote from 377OHMS:
He seems to have a vocation that is highly mobile. I can never understand it when guys that could enjoy that mobility don't take advantage of it....
Nurses are evidently in demand almost everywhere. His kids are grown, he isn't married if anything he says is to be believed. Why stay in a graveyard shift deadend in Boredom USA?
unless of course he doesn't have the vocation he claims to have
Lets assume he is a nurse, add his dreadlocks, compulsive lying, self delusions of grandeur and the safe to assume accompanying personality faults. He's probably lucky to have ANY kind of job.
Maybe he really works at a convenience store.
