Chance meeting

As I did 2 or 3 times a month I went to the park (4 miles away) at 10AM to watch the dogs training at agility (running courses with hurdles, tunnels, etc). I do not have a dog. As I approached the training area a dog, who I had never seen before, dropped its toy ball and it rolled my way. I picked it up and gave it back. Its owner, a blonde lady, approached me and retrieved her dog. She asked me if I had a dog. I said no. I introduced myself and she then "told me her first name". It was a slightly unusual name. My brain then clicked her name with having a dog. I had that morning at 8AM been matched with her on Great Expectations, which I had only joined three days earlier. I had not read her profile yet. I had merely scanned the page and had only seen the first name (that is all they give) and that she liked dogs and riding horses. I must of spooked her when I started putting 1 and 1 together in front of her. She must of thought I was a stalker. We never did go on a date. I contacted Great Expectations and they said that (as far as they know) no one has ever met their match accidentally. So, in West Los Angeles (a lot of people) what are the odds?
