hmm.
gents - going out for a few with members of your division alongside is one thing. crashing over at the house of someone you work with (and may be the DO of) in a seagoing appointment is quite another. i have to say that although no one here is in full possession of the facts, the Lt in question put the junior/snr rates she was spending her time with so closely in a bad position which was unfortunately only likely to turn out one way. badly.
unfortunate indeed, for all concerned. have a drink with your people - then thin out and let them get on with it.
