The frustrations of having a passion for things that everyone thinks they know but really don't (books, film, music, sports, art, current affairs, animals, whatever), and being almost solitary in one's disparagement (disgust perhaps for some, but too strong for me) of others who claim or attempt to be a fellow connoisseur, or simply a (bad) player, in one's field.
i.e. How can I engage in a conversation with you at an intellectual level above that of petty gossip, when you don't understand a thing I say, or you think you do and then respond with stupidity and then try to teach me things I already know or don't care to know?
and. How can we bond by participating in joint activities when one of us will always derive more satisfaction than the other simply due to personal differences in understanding/love of the activity at hand? Resentments are sure to arise sooner or later against the person(s) enjoying the activity more, and if that person is me, without a doubt I am sure to disparage you. (Or perhaps you will disparage me, if said activity is cycling, or anything requiring muscle movement.)
I am tempted to give examples but I probably shouldn't. If you've felt anything similar you wouldn't need examples anyway; you'd have your own.
