Continuing coincidences

As a young teenager my son fell in love with a girl a little younger than himself. He arranged for me to meet up with his mother as he was sure we would get along. We discovered that we were both the same age and were born on the same day. We both were on our second marriage and had each had two children, a girl first and then a boy, and both named our daughters Holly. Her name was Jane, which was my middle name and we were both stepmothers to children born to in the earlier marriages of our respective husbands. (and yes, we did get along very well). Two or three years later my son was returning home from a three month trip abroad with his girlfriend and mentioned that it would be good if he could get home for 1st September. His girlfriend asked why and he told her that it was his parents wedding anniversary. Yes - it was Holly's parents' wedding anniversary too! I was quite glad when my son and this girl parted - it became a bit spooky!
