My uncle did one stint in the Marine Corps, about a bazillion years ago. Still considers himself 'a Marine' because 'Once a Marine, always a Marine.'
Okay, fine, but what does that really mean?
I was Navy for 20 years, but i don't think of myself AS a sailor right now.
As a sailor, if tge ship caught fire, i ran towards the fire. Right now, if the building even goes so far as to have an acrid smell, i leave.
As a sailor, i saluted those appointed over me. Four months ago, i told my supervisor to shut his whore mouth.
The military steals several days worth of pay each year. The pay is based on a 30-day month, even though more months are 31 days long. Even getting overpaid in Feb, they still get six free days per year out of every Tom, Dick, and Hortense in uniform (five in leap years). Now i get paid by the hour.
I have worked on energized gear to support the ship's mission in conditions that would probably make an OSHA manual burst into flames. Nowadays, the only book that bursts into flame around me is the King James.
