In a previous life I was party to the hosting of VIP visits to my work place and the visits from the Variety Club Of Great Britain struck a chord with me. Initially I had no knowledge of the cause when I unwittingly remarked to a fellow and more knowledgeable host that the visitors seemed to be very young (not one was of teenage years) and maybe what we were showing them might be a a few years before their time to understand and appreciate it.
My fellow host looked at me and said, I take it that you haven't hosted this type of visit before. These kids he said are all terminally ill with only months to live and next year we will host another visit but ... there will be a different group of faces as the ones you see now will no longer be with us.
