I'm an ex-Marine.
Marines, stop whining about the word "ex-". "Former" & "Ex" mean the same damn thing. In fact, for a culture that celebrates acronyms and shorthand slang, I'm surprised that so many get caught up by this meaningless distinction.
In fact, "Former" is worse, because it's an extra syllable and three extra characters that you have to write or type. Marines are all about efficiency, so this meaningless distinction baffles me.
Marines, stop getting your collective panties in a bunch about this.
