Oh Finy, you beat me to the punch! Haha, I've been meaning to ask this question since discussing it with my brother-in-law and his fiance. I don't like swearing, but I do find I do it when I'm angry or taken by surprise,
Sh#t yeah, all the f#$%ing time....;)
To be honest, they're just words, so in our house, you'll get in trouble if you tell someone to shut up, but if you say you thought the movie was cr&p, it's not an issue....
I do tell the kids if they swear, their friends mothers may not let them play with their kids, and interestingly, my eldest doesn't swear at all (and never has, even though it's not a big issue in the house)
