Treasure your friends - and let them know it. I go to a weekly dancing event and always met up there with somebody very special. Joan was a wonderful dancer, who loved to sing along to the music as she danced. Always had a good, kind word for everybody and made wonderful conversation. A highlight of my week was meeting with her. I attended the dance in Melksham, Wiltshire, last night and learned that she and her husband were murdered early this week - no apparent reason. I am devastated. but feel privileged to have known her, and resolve in future to let friends know how I value them in my life.
