Dan Carlin (@dccommonsense) is an amazing storyteller. In the latest episode of his podcast Dan Carlin's Hardcore History, he speaks at length about idiosyncrasies. He explains that idiosyncrasies only matter when the person is a well-known personality and those of your average John Doe really don't matter. While this is the simplest explanation of some of the infatuations of our tabloids, it got me to think about idiosyncrasies in a micro-sense in my personal life.

An idiosyncrasy is an unusual feature of a person (though there are also other uses, see below). It also means odd habit. The term is often used to express eccentricity or peculiarity.[1][2] A synonym may be "quirk".

Why do I care about that hear-me-out-completely attitude of my father or the lack of punctuality of a friend? They are important to me in my life. 

While I know those idiosyncrasies are probably not going to go away, I keep reminding them, pointing it out why some of those annoying ones are really annoying. I give up after a couple attempts but it sticks in my head. For a smaller subset of these guys, I actually don't stop and keep pointing it out over and over. These are people even more important.
