Here's an amusing passage from Ysenda Maxtone Graham's book The Real Mrs Miniver: The Life of Jan Struther, her biography of her grandmother.
It's an anecdote told by Jan's husband Tony about his father, Jim:
"When my father was a young man, he was at a dinner party in Perthshire, a grand affair, all the men in their kilts and doublets. He sat next to one particularly attractive girl, and he reckoned he was doing rather well with her when he felt her hand on his knee. He thought he was in for an exciting evening. That was during the soup. During the fish she gave his knee a comforting pat from time to time. But I'm afraid that when the joint was served, all that happened was that his hairy knee was offered a morsel from the fair lady's plate."
The book is an extremely interesting read, by the way, though not at all what you might expect to be the life story of the creator of Mrs. Miniver.
