I had a situation in my family when my father's older sister married a man and they had a son who married my father's youngest sister ..They then had children. It was always funny how the different members of the family thought about their relationships when they were asked " who the other members were.?" The whole family were coming from a Yale football game in a large car and they were speeding and were stopped by police. The police asked who they were. The answers were amazing as each member of the family gave the police different messages as to who they were. Like Uncle was also Grandfather and the like. Harry Taylor
