Good point. Not everyone swears like a trooper. I'm ex British army so can live with it. But I wouldn't swear in mixed company or in front of my daughter, even though she is over 21.
To each his own, of course, but coy swearing is still swearing.
Actually I do sympathise. I swear too much (but not more than the average Aussie) and wish I could train myself to use some other intensifiers in my language but most of them lack intensity.
By Jove!
My word!
Sweet zombie Jesus!
Drokk!
