When I was an elder and group overseer - it was the day of Princess Diana's (Saturday 6th Sept 1997) funeral - and even I could see this wasn't the best idea to go knocking on doors.
The UK - especially England - had lost its stiff upper lip in a week of blubbing and emotion and I will admit I was effected too by the wall-to-wall images on the TV from the news channels.
I made the decision that "my" group would not have an arrangement that Saturday morning in view of the public mood, many of whom would be watching the funeral cortege on TV.
There was another elder in my group and his wife (who I got on very well with) phoned me up to lambast me and tell me how bad she thought it was that there was no group.
I said "fine - if you or any one else want to go out you can have the map and go - but for me and mine; we're not." She was not a happy bunny.
Of course some ubers went out, doesn't every hall have some? Less now thankfully.
