When my friend's husband died, after a long and happy marriage, she said that she would never find another man like him, and couldn't contemplate the thought of marrying again. Jokingly I replied, "Never say 'never'!" The following Christmas a widower, who had been friendly with both of them, asked her to accompany him to the Christmas dinner at their local club. Flustered, she refused, saying that everyone would be staring and talking. I persuaded her that there was no harm in two people who were on their own sharing a social event. She went with him, and they started going out for walks together. The relationship progressed over the next few years, and I could see love blossoming.
Sadly, her friend died of cancer, quite suddenly, so she was bereaved a second time, but they both gained a few years of happiness together, though still living apart.
