Hmm now that I think of it, I don't think I've uttered a real curse word for a loooong time (ie: the f-word and friends). I might mention "bullshit" once every few weeks, (I didn't study my ass off for a B.S. in Computer Science for nothing
) but otherwise my mouth is always sparkly clean
Why? I dunno.. I just never felt the need. I always found other ways of saying things without resorting to curse words.
Of course in my head, I mentally project plenty of obscenities at inanimate objects when they fail to operate as I expect them to (ie: "Yarrgh! Another paper jam! Fuck you, DeskJet, you fucking fuck!")
