Each Friday night I drove my wife to the station for the train to California so she could visit her sister who was ill. Ten minutes later, my sister arrived by train from Sacramento to manage our household over the weekend.

On Sundays this procedure worked in reverse with my sister departing by train ten minutes before my wife arrived. One evening after my sister left and while I awaited my wife’s arrival, a porter sauntered over. “Mister,” he said, “you are sure some man! But one of these days you are going to get caught!”
