Well here's a story that doesn't spoil any surprises, unless you have a roommate like I had.
This guy was a bit of a heffer. He was on the NUPOC program back in the day before BDCP was fashionable, so he was getting cash all through college so that he would go to OCS and then go to nuke power school and onto subs. I guess after four years of living the cush lifestyle, OCS was a bit much for him. My roommate decided one night that he was going to leave, and he did. Just walked out of the room without waking me or the other two guys in the room and drove off. He came back a few days later and was placed in GTX or whatever the hell that company is called now. I guess after he tried to cut his wrists with a plastic spoon he was found NPQ and sent home. Didn't have to pay back the tens of thousands of dollars he was given during his time in school.
