In general, I keep to myself fairly often, and that includes my interests. In particular, my love for professional wrestling is something that I don't really discuss with most people. Now, I know this forum site is different, but I doubt me talking about wrestling with most people would not end in something like "oh, you like that fake stuff." Oh yeah, "fake" is probably the word I dislike the most that people use to describe pro wrestling. I prefer things like "scripted" and "pre-determined." I feel like telling those people "Yes, it is a performance, but it's not 'fake' like movie special effects" or something like that. So yeah, it's not really worth the time to mention it to most people.
Along the lines of that, I tend to develop an obsession about my wrestling video games too. I'm a bit strange because I like to "sim" wrestling matches, by having CPU controlled wrestlers face each other, to find out who would win. Kind of defeats the purpose I guess of a video game, as the playing part is what it is supposed to be about, but watching wrestling matches is even fun to me in the video game world.
