Quite unpleasant.
While I was peacefully riding home, after a long workday, a donkey on a worthless 80.000€ SUV (worthless because he may have bought it, but he can't drive it if he's unable to pass a bicycle on a multiple lanes road) decided that the lane and the whole road were too small to contain his ridicolously enlarged ego, and started to annoyingly blow his horn, probably in an attempt to force me to disappear from his view.
Unfortunately for him, I graciously waved at him and took the lane.
He continued to blown his horn all the way long, until he discovered the existence of another lane and proceeded to pass me, insulting me, my parents and probably my ancestors, too. At the next traffic light, I noticed his rolled down windows and I called him by name, giving him an honest advice: "Donkey, learn the Road Code and get a compact car, since you can't drive properly the outrageously expensive SUV you bought". I then invited him to pull over after the intersection, in order to discuss the matter in a more personal, frank manner. But he unexpectedly declined and speeded away.

Sorry for the rant, but I'm kinda allergic to idiocy.
