.. because they have strange personalities. I was introduced to a a motley of personalities when I stepped into the gates of my undergraduate institution and even more after I walked out of those gates. The good thing about undergrad life is you pick a douche and tell to him/her about their weirdnesses on their face but outside the college walls everything needs to be packed in foils of diplomacy.
Hate those bad self learned guitarists who relentlessly practice on a cheap guitar with a flat learning curve. And if the person is an introvert to the extent that you cannot predict the response to harsh (but true) reviews like these then you are facing an ugly social quandary. First the the rate at which the strings are pulled is so low that between the notes Christopher Nolan could have create some breathtaking action sequences at just 2nd or 3rd levels of inception. Next every piece that is played has only 2 to 3 notes which are put into a seemingly infinite loop. Is he trying to run a Monte Carlo simulation of some lame guitar notes?? There may be more notes from his perspective but trust me they all sound the same - pathetic. Sometimes he mixes these sounds with his terrible vocals, only to add fuel to the unwished fire.
Years of evolution doesn't bring a rational sensibility that is assumed to prevail in human actions. What do we call those people who walk away silently from requests to group formations? It is hard to say a 'no' but silently walking away makes the who scene more awkward for everyone. People tend to unconsciously become over-picky on such small things only to make themselves weirdos.
All the advancements in technology in every breadth of social-life is making people more active on virtual social-networks but leaving them socially-challenged on the real ones.
