People who intentionally work extra hard to entice; frustrate and incite others into thinking, feeling or acting poorly, only for them to seek and/or find pleasure in the entire game or charade. I'm pretty sure the word is troll, or trolls. I don't wish to understand it, it's pointless! It can be frightening; threatening and certainly is nonsensical. Chances are that with too great of exposure, it drives one crazy enough to possibly expose somewhat of a contagion. It makes me think of the phrase, "rebellious dogs, all the way." It creates anxieties; tensions; misunderstanding and everything bad.
Besides this: Well, being interrupted mid sentence; having another react to what they incorrectly assume is going to be said, because the other doesn't wait to let the sentence be completed.
And, I guess feeling the need to beautify one's back yard, (what's out of site) vs. doing so with (what's visible) and in front - due to my trauma based experiences and fear, as well as, the real possibility of encouraging further acts of perceived just revenge - all annoying.
But, the first parts are the most annoying as I run into such more regularly.
