In my early youth, I witnessed something that stayed with me for a long time – right up until today in fact. One day, a man who drove a truck for my father broke down (the truck, not him) and needed towing to a workshop (lets call him Jim). The guy towing him, (lets call him Bill), hooked up the towrope and after a brief discussion they set off. I rode shotgun with Bill. We hadn’t gone far when Bill started to show signs of strain; on himself and the vehicle he was driving. There were a lot of expletives and cursing, (the lingua franca of the building trade back then), especially when driving up even the mildest of inclines.
