Years ago, when I was young, I knew a man who was a doctor, and not a bad one either, but he didn't practise. He spent years burrowing away in the library of the British Museum and at long intervals produced a huge pseudo-scientific, pseudo-philosophical book that nobody read and that he had to publish at his own expense. He wrote four or five of them before he died and they were absolutely worthless. He had a son who wanted to go into the army, but there was no money to send him to Sandhurst, so he had to enlist. He was killed in the war. He had a daughter too. She was very pretty and I was rather taken with her. She went on the stage, but she had no talent and she traipsed around the provinces playing small parts in second-rate companies ata miserable salary. His wife, after years of dreary, sordid drudgery broke down in health and the girl had to come home and nurse her and take on the drudgery her mother no longer had the strength for. Wasted, thwarted lives and all to no purpose. It's a toss-up when you decide to leave the beaten track. Many are called but few are chosen.
