The jargon may have changed now, but a few years ago the concept of "sunsetting" was frequently discussed where I worked. It was about putting a stop to work that was no longer needed, work whose day was over.
I thought about this as I walked home on Wednesday. I had had a very good day - put the final touches to the report I had been working on, went to buy party food, and was served a lovely cup of tea - with teapot - by a colleague. We had cakes and fizzy wine, a very short goodbye speech and best wishes passed on. I was the last one out. I switched on the "out of office", closed the front door and walked to Marble Arch through the park. An early moon was just showing through the clouds as the daylight faded. Sunsetted.
Quite a good feeling after all.
