It's a measure of respect towards other people as to how you phrase your statements, and the type of vocabulary you use. We're truck drivers,......We've invented creative swearing,........We can swear in Spanish,......We know swear words of five syllables,.....We know swear words so bad, that if you were to utter them, everyone within hearing would have to go get re-baptised,..........Have a box of freight tumble down and hit you on the head and knock your glasses off,....and you'll sound like a veritable Vesuvius of profanity,.......sulphur and brimstone would pour out the back of the trailer you're working until you've found your glasses,...........If there was a Ph.D in Profanity,....we would all have Masters,.....would probably be teaching the course,...(...stand still while I drop this box on your head....)........So,.....as I said,...it's a matter of respect when you talk to a supervisor, or a dispatcher, and you choose respectful and thoughtful words...........Besides,....you don't want them to embarrass themselves by trying to impress you with their weak, milque-toast version of what they regard as swearing,......It'll make you cringe, watching some red-faced lower-management type struggling to utter some mildly foul explicative,.....knowing that he's at his absolute limit for his capacity of harsh and offensive language,...........and you're trying hard not to smirk because you've heard truck stop waitresses use the same language as a term of endearment to their customers. You've probably heard nuns using sterner language........It's amazing to me why a supposedly educated manager would try to impress us truck drivers with their weak and imperfect command of scatalogical language,......when we've heard what Real Swearing,....by Real Men sounds like......Try not to laugh in that manager's face when he dribbles out what he considers strong language,.....but what we all know as the second-rate cussing of the boy you used to give a Dutch-Rub to on the Junior High School playground..........Embarrassing to hear....
