Mine was more unusual than romantic. We worked together. She was attractive but quite a bit younger than me, so I always remained aloof.
At the time I used to go rock climbing and one weekend, at a tiny place near Wrexham, I had a fall and snapped my femur in half. When someone called my workplace on the Monday to let them know, it was she who took the call. I was told some weeks later that she was utterly distraught.
Once I got back to work we became close and had about 5 years together.
