Two friends of mine swear liberally in front of their 2 year old daughter. It's something that puzzles me, growing up as... conservative as I did. But, y'know, for them it's not a big deal obviously.

I still never swear in front of my parents. But Afrikaans is such a nice cussing language, it'd be a shame never to let loose a few choice descriptives now and then. Heh.
