In March 2007 I went on my first skiing holiday with my husband and son. We stayed in a catered chalet in Meribel. Amongst the guests was an airline pilot in his late 50's who was holidaying on his own. We chatted over dinner a few times and said goodbye at the end of the week.
Two years later, in December 2009, my husband, son and myself were with friends on a skiing holiday in Valmorel in France. We had flown into Chambery and enjoyed a week's holiday on the slopes. On our return journey, we travelled to Chambery and after a two hour wait, were told that due to weather conditions, we would have to be bussed to Lyon and fly from there instead.
We arrived in Lyon airport and whilst waiting for our flight to be called, I was chatting with my female friend about my first skiing holiday and the nice Pilot who had graced our dinner table in the chalet in Meribel two years before. At the same time that I mentioned his name, someone tripped over my son's suitcase and when I turned to apologise, it was that same Pilot!! Now that is a coincidence!
Another time, I was in London on a day-trip with my step-daughter and her friend.
