The UK and some other countries commemmorate their war dead with a poppy.
A few years ago, the Royal British Legion decided to add a leaf to their poppy symbol. Almost immediately the "My way or the highway" brigade started to try to dictate to everyone how they should display their poppies. They were particularly fond of saying that the leaf should be positioned at 11 O'clock in memory of the 1918 Armistice. That was one war. There have been so many since.
In 2022, I wrote this in reponse to that nonsense.
