My dad always saw someone he knew when we were nowhere near home - one time in LA Airport!
But my favourite anecdote came from his brother, my Uncle. He was a doctor, trained in Edinburgh, and then went and lived in Africa (think Nigeria) where he did research into Malaria. (He even had a pet cheetah which he rescued and had on a lead, and a talking parrot!) He was in the bush, and one of his boys (this must have been the early 1950's/late 1940's maybe) came running up saying there was a 'white man coming'. So he was welcomed, fed and watered and they got talking, when my Uncle said "how's your Susan?" The man looked astonished, as it turned out that my Uncle had gone to school with his sister!
My Uncle Bob was a larger than life character and had many, many stories - I spent my honeymoon at his house built on the side of the cliffs in Maple Bay on Vancouver Island, from which you could see whales passing in pods, and eagles sat on the trees below, and he hired a car for us to drive around the Rockies, fabulous! (Since very much divorced though!)
