"The title was something like "Manners for Nice People who sometimes say F**k". I'm one of those"
thatbags - that made me laugh. I am one of those too. People who think I am nice (and I am, generally,) are often shocked that I use some of the words I do when ranting. Most of my x-rated stuff is in frustration at myself, I should add! I can turn the air blue in the kitchen.
Not only that, some people think that over 60s are either miserable old bags or saintly pillars of the community. I find that strange. We are products of the years in which we've lived. My Mum used "ruddy well" when she was annoyed and any other 'bad' word was strictly forbidden at home. Nice girls didn't swear (or 'cuss' as she called it.)
I don't like unnecessary bad language in polite company, ever, feeling I have a wide enough vocabulary to avoid it, but I suspect that even my grown children imagine I am a bit of a prude because I am their mother. If only they knew - not just the language I am capable of using, but the erm..fruity adventures I've had too. It would make their hair curl!
