bermuda flight coincidence

I was returning on a flight from London/Bermuda when with about 45 mins to arrival, the captain gave out a message over the intercom.This prompted the young lady sitting next to me , who had previously not spoken , to ask me if I had flown direct from London.I replied Manchester, wherupon she said she had flown from Nice.She then said she was Bermudan & was coming home to arrange her wedding to the father of the 13yr old girl sitting next to her. She then said she worked on a luxury yacht based in the South of France, whereupon I replied that my son was a captain of a yacht & was also off Nice,she asked me the name of the yacht , which I told her & explained that he had just moved onto a new one. She then got very excited & was able to tell me my sons name & indeed that she had had dinner with him& her partner the previous night in Antibes ! She then told me that the young girls father whom she was marrying had just left the yacht he captained & my son had taken over from him. What a coincidence being on a flight to Bermuda & sitting next to someone who had dined with my son in the South of France the previous evening !! Also her husband to be , coincidentally ,had the same surname as my son !!!
