Seriously, how rude and self-involved do you have to be to be so utterly convinced that you are right and I am wrong about something as to come and bang on my door just to tell me so? To ask me "is that so?" when I tell you I am not interested, like I don't know my own mind and desires. To think so much of your own opinions that you automatically discount mine and my knowledge of my personal needs, tastes or wants? Clearly it isn't a level of rudeness that exceeds human capacity, alas.
