In old age, the legendary Lady Diana Cooper had a minor driving accident, hitting a bollard by the road. She instantly gave up her car.
Her son, John Julius Norwich, told me that her agonised response was ‘What if that had been a child?’
She loved her little car, but that decided her to renounce it.
Whenever we read of an older person causing a serious accident involving an innocent victim, many of us ask ourselves if it’s time to quit.
