“There is plenty of work for love to do.”

“And then the second thing you have to do is go and see your son. That is a duty of love, Andrew. It's as simple as that. A duty of love. Do you understand what I'm saying to you?”

“Many waters cannot quench love: the anthem's setting remained in her ears, repeating itself; a tune so powerful that it might gird one against the disappointments of life, rather than make one aware that our attempts to subdue the pain of unrequited love - of impossible love, of love that we are best to put away and not to think about - tended not to work, and only made the wounds of love more painful.”

“That, said Isabel, is the most painful feature of lost love. you wonder what the other person is doing. Right at this moment. What is he/she doing?”

“Most morality, thought Mma Ramotswe, was about doing the right thing because it had been identified as such by a long process of acceptance and observance. You simply could not create your own morality because your experience would never be enough to do so. What gives you the right to say that you know better than your ancestors? Morality is for everybody and this means that the views of more than one person are needed to create it. That was what made modern morality, with its emphasis on individuals and the working out of an individual person, so weak. If you gave people the chance to work out their morality, then they would work out the version which was easiest for them and which allowed them to do what suited them for as much of the time as possible. That, in Mma Ramotswe's view, was simple selfishness, whatever grand name one gave it.”

“And if there's bad behaviour," Mma Potokwane went on. "If there's bad behaviour, the quickest way of stopping it is to give more love. That always works, you know. People say we must punish when there is wrongdoing, but if you punish you're only punishing yourself. And what's the point of that?”

“She imagined what it must be like to have Charlie's mind - to believe that red shoes are faster then other shoes; to believe, as he did, that ducks could drive fire engines and that pigs built houses out of bricks and straw. There were plenty of people who weren't three-and-three-quarters who believed equally implausible things...and when to war over them.”
