Poppies must be a more lasting tradition in the UK. I haven't seen poppies or sellers in many decades. They were a big deal when I was a boy in the '50s and '60s, but not much after that. I think they were largely forgotten in the U.S. as the WWI veterans died out. Too bad. I remember celebrating Armistice Day as a boy in the 1950s, with its focus on 11/11/18. I seem to recall the use of "Remembrance" Day for a while before we settled on Veterans Day. But poppies? Haven't seen them over here in decades.
Isn’t Memorial Day the US equivalent of our Remembrance day?
