As a rule I have very mixed feelings about regimented grieving and remembrance. The negative feelings I have about it do not spring from a lack of respect; in fact, rather the reverse - surely if a minute or two of silence is all that is required to perform an obligation to society, it can't be particularly meaningful? I also have a problem with the silence "inflation" that goes on, from one minute, to two minutes, even to five minutes - as if we can measure some worth by the length of time spent without vocal communication. A final thought (which applies particularly to the 11 November remembrance) is that we are remembering those who have fought and died for our freedom. Yet that freedom must by definition include the right to dissent, to disagree, and to observe those occasions in our individual ways. Rituals of death are, objectively, for the benefit of the survivors; it's not always clear to me what purpose there is to a silence, what thoughts we are supposed to collect or how they help society as a whole to move on.
I found George Psaradakis' speech simple yet eloquent.
