Perhaps I should just clarify why I asked this question, and my use of the phrase: "technically the act of remembrance has passed."
In a previous life, I served for 5 years in the RAF. Naturally, we would all wear poppies in the first couple of weeks of November and would very solemnly, and correctly, remember the fallen with collective acts of remembrance on both 11/11 and also Remembrance Sunday.
However, the service and parade on Remembrance Sunday marked the end of the official period of remembrance (for want of a better phrase). Poppies ceased to be worn after the 11am service and parade.
I always felt that this was right: of course, we would "never forget", but the solemnity of the parade and service marked a point when, at the end of it, we would begin to look to the future again.
I have, ever since, always removed my poppy after I have observed the minutes silence on Remembrance Sunday.
However, I did lead "my" two teams and circa 50 watching parents in a minutes silence before this afternoon's game. Not surprisingly, it was impeccably respected by all. I can't be sure, but I think that the teenagers skating on the adjacent ramp, and parents with toddlers in the nearby play equipment followed my cue and paused to reflect for a moment.
