He steered a steady course, carefully applying his brakes so as to allow the other driver ample opportunity to effect his passing as quickly as possible. Not that he deserved the consideration, of course, but Mr. J.L.B. Matekoni knew that when another driver did something dangerous it was best to allow him to finish what he was doing and get out of the way.

In a cloud of dust and gravel chips thrown up off the unpaved verge of the road, the impatient car shot past, before swerving again to get back onto the tarmac. Mr. J.L.B. Matekoni felt the urge to lean on his horn and flash his lights in anger, but he did neither of these things. The other driver knew that what he had done was wrong; there was no need to engage in an abusive exchange which would lead nowhere, and would certainly not change that driver’s ways. “You do not change people by shouting at them,” Mma Ramotswe had once observed. And she was right: sounding one’s horn, shouting-these were much the same things, and achieved equally little.

And then an extraordinary thing happened. The impatient driver, his illegal manoeuvre over, and now clear of the tow-truck, looked in his mirror and gave a scrupulously polite thank-you wave to Mr. J.L.B. Matekoni. And Mr. J.L.B. Matekoni, taken by surprise, responded with an equally polite wave of acknowledgement, as one would reply to any roadside courtesy or show of good driving manners. That was the curious thing about Botswana; even when people were rude-and some degree of human rudeness was inevitable-they were rude in a fairly polite way.

The road was climbing at this point, and the other car soon disappeared over the brow of the hill. Mr. J.L.B. Matekoni wondered why the driver had been in such a rush. He could be late for an appointment, perhaps; or he could be a lawyer due to make an appearance in the High Court down there.
