chivalry

i didn't notice at first (we were in a bar - not too much light), but my friend S1. had a black eye. i asked him what he'd done. turns out he had helped a girlfriend who was being harassed by a very aggressive bloke. when the guy made to hit the girl, S1. came to the rescue. thus the black eye. i hope the girl said something on the lines of 'gosh, my hero!'.
