I dunno about others, but I'm not a particularly picky extrovert. I watch trash TV because my sister enjoys it. I first got into Starcraft 2 because my brother wanted to play with me. I bought diablo because I played with my father. My best friend and I watch movies together. I think activities are what make that invitation less.. awkward. or off. Maybe. :c But I'm always willing to teach someone a new game or boardgame, or teach them to play magic or watch a series of shows with them if it means bonding with them as a result.
