My reactions differ quite a bit, depending on the situation. If I realize, in retrospect, that I said/did something rude or "off" to a complete stranger, I may take note of the mistake, but then figure, I´ll probably never see this person again, so I don´t bother about it too much (does that sound awful?) If I make a faux pas in some kind of important situation, like anything job-related (or an interview), I´ll stress about it and be very worried, often wishing I could take it back and redo it. If I offend a man in some kind of "romantic" situation, generally, I´ll be pretty clueless about it because I´ll have NO idea what I actually did wrong: so rather than punish myself, I´ll analyze, over and over again, what might have been the problem, guessing...possibly even blaming him for just being weird....
I´ve learned too that punishing myself doesn´t really work, because I´m often an incorrect judge of these things. I got a new job last year after thinking I TOTALLY blew the interview, and not expecting to ever hear from them again....and, in times when I´ve sometimes truly offended someone and did the most damage, so to speak, I was often totally oblivious to it!
