Many people write a "bucket list" of things they want to do before they die.  Now in my 80th year, I don't have the time or the energy to do things that others might aim for, but I have during my life visited many places, seen many things, and enjoyed many experiences that I would have been sorry to miss. There have also been some events that I would have preferred not to experience, but which have enriched my life in different ways, and which I remember with a kind of sad affection.  
Some of these are very personal to me, and would not be interesting to most people, but read the note if you wonder why I chose them.

Here then is what I might call
