Now you're getting it! Overachiever indeed. :beer:
That pretty much puts the last nail in his coffin as far as I'm concerned. You only go to one boot camp and only once (with a few, very limited exceptions mainly to do with medical reasons). Plus the curriculum is the same at both boot camps, except Parris Island people have flat land, but sand fleas to deal with, and San Diego recruits have mountains and a flippin' loud international airport literally right next door (guess where I went to boot camp?)
Lenny is right. Most Marines won't forget their platoon number or DIs names. Time does destroy some details, but some things never go away.
Dump the dude and hopefully achieve peace of mind. Good luck. Feel free to drop back in and participate in any of the threads you have access to. We have a very nice Canadian lady who is in and out of here frequently.
