I'm guilty of saying a few choice words. Making no excuses, but I worked 40 years in 2 industies where men are men, and very few men don't curse in some form at work. Mechanics, machinists, welders, construction workers, they all have a tough enviorment and tough work. You make a mistake or bang yourself, you get cut or burned everyday, you just say F^%$# and keep on truckin. Maybe its a product of a military hitch, where foul language is mandotory in that culture.(at least in my time) Unfortunatly, bad habits stick, and thats one of them. When you don;t have to watch your P's & Q's (old saying that should change to F's & Damn's) you usually don;t until your Mother is within a ear away.
Nowadays, that doesn;t even matter.
I worked with a few men over the years, who never cursed and were from a different generation where even the most tame of curse words were never said in the company of women and children. Thats a standard, nearly extinct.
We seem to have evolved into a society where the F-word to many is as common as it comes, and nobody is spared hearing it.
2 things that get me going is drive in fast foods that can't get your order right but rattle off 5 things to try selling you. and people laying on horns when traffic can't possibly move.
