At a recent horror group meeting, a female friend of mine was being harrassed by a drunk guy she knew from her place of work and had probably tracked her to that event via Facebook (although he claimed it was a total coincidence). As the meeting wound to a close, my companion and I were waiting for a cab (she was staying over at my place) and this guy continued to creep her out, ignoring all of her rebuffs. Finaally, I stepped in: I tried a friendly "Time to go home", then a more assertive tone and eventually - in some desperation - let him believe she was 'with' me (which she was, but not in that sense). He left. I apologised for playing the macho card, to be told she was very grateful I'd intervened; it still felt odd.
