In 2006 I was aged 60, 4 years out of a 20-year relationship that in the end became very toxic, I was retired and my mother had died 2 years earlier. I was quite content and seriously contemplating a move to Suffolk.
Then I went on a council-run "Simply Walks" walk, to get some exercise and fresh air. It was my first walk and people were friendly and chatty, particularly a chap who was very interesting and amusing, telling me about his career as a television lighting director and making me laugh. That evening I was thinking about my day and the chap, and a voice said in my head "we are going to be very important to each other".
Well, that terrified the life out of me because I was quite happy with my single life, thank you very much, so I didn't go back to the walks. But about 3 weeks later I told myself not to be such an idiot, so I did go back. The chap's face lit up when he saw me, mine did the same and we've been together ever since and happily married since 2009.
