Title says it all... What exactly get on your lasty nerve, what really ruffles your feathers... Y'know! For me, it's strangers who talk at you in public places. And I mean AT you... They just start talking, no hello or anything, offload all their personal history on a subject, and don't get the hint that you are not interested in the slightest! It's especially worse if it happens at the end of a working day, and all you wanna do is get home. Weirdest one I've had is a guy who wanted to talk about music from the 1950's... He actually referred to himself as the "Rock and Roll Encyclopedia", I shit you not... Anyone else wanna share?
