I'm kind of annoyed by people that go back on their word, or go against decisions that have been made. When a bunch of people unanimously decide something, and some self-proclaimed bigwig comes in and decides to veto the will of the masses, that ticks me off a little. I suppose some higher-ups can't help but assert their dominance over everyone; in fact, they love it more than their responsibility. Seems to be a common trait among those with power.
