Whilst we are on the subject of friends many people, particularly those in the same organisation or workplace who are part of a group of colleagues who have worked together for many years often make friendships which carry over when they retire. Of course some people move away when they retire or do not live anywhere near former colleagues. In my case I live on an island (and, yes I appreciate that Britain is an Island but I think you understand what I mean) as do a significant number of my former colleagues. So getting together is relatively easy.
In my case many of my former colleagues live in and around Stornoway. I retired from the local council 30 years ago. On the first Wednesday of every month we have a lunch club for retirees. We call it The Last of the Summer Wine Club. My readers in the UK will understand that reference. For those who do not there is a television programme which was on television for 31 years from January 1973. In short three elderly men from Yorkshire prefer to stay young by engaging in "youthful" activities whilst reminiscing about their childhood days. I enjoy watching it now as much as I did half a century ago - it hasn't dated one little bit.
