Precisely. The shock + blur combo.
I was a complete idiot about reporting. My orders said to report to the quarterdeck between 1300-1700 at (must have been NIMITZ?). I had an early flight from Jacksonville, FL to Providence, found something to eat at PVD and took a taxi. I reported in promptly at 1300, figuring I would put my stuff in my room, wander around a bit, get acclimated. The people at the quarterdeck were very nice, stamped my orders, collected paperwork, had me sign something and kindly escorted me to a swinging door. I went through the doors. The blur began. The people in the other side of the door were not nice. It was me and 2 others for the first 2 hours. The prior enlisted? Skidded in at 1645, of course, including my roommate, a treasure trove of survival tips and pro savvy.
