In August 2010 my husband and I were on a river cruise in Russia. On the first evening we were socialising with our fellow guests. We got on well with a couple from N London (we live in Mid Wales) and started talking about our families. At the time our eldest son was a trainee solicitor in a large London law firm. It turned out that their daughter worked for the same company and his second seat had been in her department. They sent her a text telling her this, so she was able to go up to our son the next morning saying "Our parents have just met up on a boat in Russia!"
My husband, his sister and our younger daughter all share the same birthdate, 24th August (1946, 1954, 1982). My elder daughter and my father ( now deceased) also shared the same birthdate, 4th February (1916 and 1981)
While doing her cabin crew training in London in 2006, my younger daughter made some good friends, two of whom came to stay with us at our home in Mid Wales. One girl knew that before she was born, her family had lived in Wales. She was surprised to learn from her parents, that they had lived in the very town - Builth Wells, Powys - that she was soon to visit.
