Serendipity: the occurrence and development of events by chance in a happy or beneficial way.

What were the chances… “You’re going to Santorini when?” My husband and I had booked our Windstar cruise of the Greek Isles and two weeks before we were to leave, I found out that a couple from my hometown — very good friends that I’d known most of my life — were going to be staying on Santorini the same week we would be visiting from our ship.
