My wife is from the Sheepshead Bay area of Brooklyn. She reads a web site from the NY Transit Museum (cool place I’ve been to a few times). Some commenter asked about people’s favorite subway stop. She replied giving one near where she grew up. Someone responded asking her where she lived. They exchanged a couple notes and then she asked where he went to school. PS 225, same as her. Then she remarked that her father was a shop teacher there; did he remember him? He sure did. And then he said that her father, on discovering that he was a serious pianist, invited him to their apartment to play some piano and that there was a girl there. Was it her and did she remember? Yes, she was ten years old but she certainly remembered the occasion.
Mundane and pointless, but what a coincidence!
