MOTHER TERESA!

I only swear around people I know don't mind swearing, or online. At work it's extremely rare that you'll hear me swearing (I once swore on a night out and one of the guys I work with was really shocked, I found that amusing), I don't swear around kids or my Dad or my stepmum. Probably not around most family members aside from my Mum and sister, actually, and that's pretty rare too. However if I'm with people who are comfortable with swearing, it's just like another word in the vocabulary for me.

Also, New Zealanders and Australians swear so much better than the rest of the world. You guys don't put enough effort into the passion behind the word!
