Johannesburg - Some years ago, I saw an old geezer drive an ancient skorokoro bearing an interesting sticker that read: “All parts in a car are important, but the most important one is the nut holding the steering wheel.”
I felt like shouting at the top of my voice: “You go, old man!”
But on thinking about it further, I felt that it might just turn out to be one of those aphorisms that fly way over the heads of many people.
