Old friends, like old shoes, are comfortable. But old shoes, unlike old friends, tend not to be supportive: it is easier to stumble and sprain an ank… - Alexander McCall Smith

And how we become like our parents! How their scorned advice – based, we felt in our superiority, on prejudices and muddled folk wisdom – how their opinions are subsequently borne out by our own discoveries and sense of the world, one after one. And as this happens, we realise with increasing horror that proposition which we would never have entertained before: our mothers were right!

The thought of Mr. J.L.B. Matekoni nursing secret, unfulfilled ambitions saddened Mma Ramotswe, as did the thought of people wanting something very much indeed and not getting the thing they yearned for. When we dismiss or deny the hopes of others, she thought, we forget that they, like us, have only one chance in this life.

But we make such mistakes all the time, all through our lives. Wisdom, I suppose, is seeing this and acting upon it before it is too late. But it is often too late, isn’t it? – and those things that we should have said are unsaid, and remain unsaid for ever.
