Address coincidence

A few years ago I and three of my closest friends all lived at number 15 in their respective road or street. I lived, and still do, at 15 Chaffinch Road, Beckenham. My closest male friend at that time lived in Christchurch, Dorset, at a number 15, and two other female friends lived at a number 15 in Penge and Sydenham in South East London. Incidentally, in my childhood and adolescent years, from age 5 to age 27, I lived in a road that formed one half of a horseshoe. For the last 35 years I have also lived in a similar road that forms a half of a horseshoe. I did not realize the coincidence when I bought the house. The house of my childhood did not have a number! On another tack, I very often think of a famous person, and find a few days later that they have passed away. I wonder if I am the only person to do this?
