One boy she had known at school had borne a Setswana name which meant Look out, the police have arrived. The poor boy had been the object of derision amongst his classmates and had tried, unsuccessfully, to change the name by which he was known. But names, like false allegations, stick, and he had gone through life with this unfortunate burden, reminded of it every time he had to give details for an official form; looking away so that the person examining the form could be given the opportunity to smile, which they all did.

“Even if their names are not their fault,” said Mma Makutsi, “the way those boys behave is their fault, Mma. There can be no doubt about that. And those boys are very lazy, Mma. They are examples of what I am talking about.”

She looked sternly at Mma Ramotswe, as if challenging her employer to contradict her. Mma Ramotswe did not rise to the bait; Mma Makutsi was rather assertive-and she admired the younger woman for that-but it did not help, she had decided, to engage with her too much when she was in mid-theory. It was best to let people have their say, she always felt; then, when they had finished, and had possibly run out of breath, one could always lodge a mild objection to what had been said before.

Mma Makutsi peered in the direction of the garage and lowered her voice. “Have you ever seen those two young men walking?” she asked.

Mma Ramotswe frowned. Of course she had seen the apprentices walking; they walked about the garage, they came into the office to collect their tea, they walked to the tree under which Mr. J.L.B. Matekoni's truck was parked. She pointed this out to Mma Makutsi, gently enough, but not so mildly as to prevent a firm refutation from the other side of the room.

“Not that sort of walking, Mma,” said Mma Makutsi. “Anybody can walk across a room or round a garage. Anybody, Mma. Even those two lazy young men. The sort of walking I'm talking about is walking from one place to another. Walking to work. Walking from the middle of town to the National Stadium. Walking from Kgale Siding to Gaborone. That sort of walking.”
