She realised, though, that such a threat meant nothing to them, particularly to Puso, for whom the idea of being thirty was inconceivable. Motholeli was a bit more prudent—she had seen how a world could draw in—but her younger brother, not yet ten, felt himself immortal. That would change, of course, but traces of that attitude, she thought, lasted well into adult life, and had to. The realisation of our mortality came slowly, in dribs and drabs, until we bleakly acknowledged that everything was on loan to us for a short time—the world, our possessions, the people we knew and loved. But we could not spend our time dwelling on our mortality; we still had to behave as if the worst would not happen, for otherwise we would not do very much, we would be defeated and give up.

That Saturday the children would not be going to the supermarket, as they had things to do with friends. Motholeli was going with her Girl Guide group to Mokolodi, for a nature talk from Mma Ramotswe’s friend Neil Whitson, and Puso was accompanying a friend and his parents to their farm. So Mma Ramotswe did her shopping by herself, hesitating by the sweet-biscuit shelves and surrendering to temptation; succumbing further at the bakery section, where she purchased a dozen sugar-dusted doughnuts; and exposing a final weakness on the way out when she paused at the newspaper counter and bought two expensive packets of ostrich biltong.

Her next call was the President Hotel, in the centre of town, where she sat at her normal table, the one on the left-hand side of the veranda, looking out over the open square below. The waiter, who knew her well, brought over a pot of red bush tea unasked, and a large fruit scone. She sat back in her chair and contemplated both with satisfaction. The world was an imperfect place—as the events of the last few days had demonstrated—but within that vale of tears there were many sites and times of quietude and contentment, and this place and this moment on the veranda was one such.
