When I was a small boy in Ireland my parents would take us to our grandfather’s farm near Castlecomer in County Kilkenny. On the farm there was a hired man whose name was John Brennan. John lived in a thatched cottage about half a mile away. In the evening after the cows were milked, he would sit on a large flat stone outside the stable door and smoke a stained clay pipe. Sometimes I would sit beside him and he would tell me stories.
