Oh god. Fuck. Da- I intended to type something without swearing, so started with Oh God, and then that was my automatic response.
I swear all the time, and most of my friends do too. It's not to fit in or anything, as I'm probably one of the least constrained people I know, but we just do. I've never quite understood people who have a problem with swearing, to me it's just another form of emphasis, albeit one that has a minor taboo attatched to it. I have a friend who will casually refer to me as "nigger" in public, despite the fact that neither of us are black. He doesn't do it with any sort of malicious intent, or in order to be accepted by society, he just does it. I guess some people just like swearing.
