She had been silent, but now she decided to broach the subject. At the Botswana Secretarial College, where she had obtained the hitherto unheard-of result of ninety-seven per cent in the final examinations, Mma Makutsi had been taught that it was always better to raise issues of office procedure rather than to brood over them. “There is nothing worse, ladies, than muttering about something,” said the lecturer. “If something is wrong, then raise it. Not only is that better for you-nursing a grudge makes you far less efficient in your work-but it is also much better for your boss. So spit it out, and always remember this: a problem shared is a problem solved.” Or had she said, A problem shared is a problem halved? It was difficult to remember these things when there were so many proverbs jostling to give advice. Locusts do not land only on the land that belongs to your neighbour. The person who lies by the fire knows how hot it is… And so on; all of these sayings were undoubtedly true, but might still quite easily be forgotten-until the moment you found yourself doing exactly the thing that the proverb warned you against.
