My secret vice is that I do not own a television. In the US, that is truly perverse by the culture's standards. My mom #1 (as opposed to Mom #2, yes two mom's, only one is a lesbian, both are my genetic parents, do the math) owned a TV for maybe 2 years. During that time, we watched a lot of PBS nature shows, and then shut it off. I recently owned a very nice TV for watching movies, but I found a second-run movie theater near where I live that serves beer and pizza. I finally sold the TV when we hadn't turned it on for almost a year. Occasionally, I watch the television at the laundromat near my apartment, but I tend to cringe at some of the things I see on broadcast.
Its a pretty rare conversation I have in which someone doesn't express a newscaster's opinion as their own, or talk about some product they saw, or laugh at some truly funny joke for which I have zero frame of reference. This isn't criticism, just an observation. TV is such an ingrained part of US culture that most folks in the states don't even know when they are not relating in TV terms.
Instead, I have lots of hobbies. Hobby-wise, I write short fiction, brush up on my truly atrocious Spanish, Russian and Latin, make art, get pierced, continuously quest for the finest micro-brew, write love letters on behalf of my friends (ala Cyrano deBergerac, except I don't love any of them, and none of the subjects are my cousins), routinely destroy and rebuild every portion of my home network, and read and re-read a lot of 'howtos', such as the Hagakure, Democracy in America, and the Elements of Style (shit, I just read a lot- I have a pile of 14 open books by the bed, 9 more by the computer, and 3 on the couch. I am reading any 5 at any given time). I also cook, since I have previously worked as a chef in the past, and I still come up with new things to try out with food.
Some of my vices are true vices, in the biblical sense. However, the vices wouldn't be secrets anymore if I told you, now would they? Maybe you can pick them out of my .sig?
