Some of the above about siblings gave me the nerve to ask about boyfriends and girlfriends.... isn't the fraternization policy that you can't date within your own company?
Yes. If it gets serious for two in-company star-crossed ones, and to avoid slithering around under the radar, usually one of the pair asks to "love chit" out of the company to another. Plebes can only date other plebes, not in same company. If they are moving in a batch, and land as new youngsters in new company, they can then date other classes, except plebes, and not others in their new company.
If a plebe from Origin Company and upperclass from Destination Company have been gazing moon-eyed at each other from afar, and then find themselves in same company, USNA is not going to worry about it. They will figure out a path, preferably a good one, and it's their responsibility to know the Regs. [emoji16]
