But now I am myself d'un certain age, I know why they did it. They did it because you can't rely on the big stuff. Friends desert you. People you love die. There are earthquakes and bushfires. The Christian-fascists go on relishing their hate. Your health deteriorates. You lose your job. Your young hopes are unfulfilled.
So you learn to be happy in small things.
Like my mother and grandmother before me, my happiness is made up of these small things. Just as well, really.
