I was utterly shocked when she died. The reaction from Dub-dumb land varied: Some sister were very upset, most were utterly shocked, but everyone was advised not to talk about it at the Kingdumb Hell before or after the meetings. We should be talking about spiritual matters and not some icon who had, after all, never turned in a Field Serve-Us Report in her life.
I can well believe that a number of Dub went out knocking on doors the day of her funeral. Since literally, half the planet was home watching the funeral, Witnesses could take advantage of this by showing that they are "different" than the world and that they "do not mourn as the rest do". It's the same damn thing when they have ASSemblies on Christmas and Boxing Day where they go out of their way to show that it's not a special day at all and that doing the Lord's Borg's work is numero uno in their lives. To many Witnesses, it's almost a point of honour with them to purposely go out in Serve-Us instead of doing something normal that everyone else would do. Hell, back in the early 1940s when Witnesses were strongly discouraged from even getting married, there were fanatical Dubs who would purposely miss their best friends' wedding (because they dared to go against the advise of Judge Booze-fraud), by going out knocking on doors.
I do remember though a couple of years after Diana died, there was an article in either the Craptower or Asleep magazine on Landmines. On the front inside cover, there was a famous picture of Diana with a land mind victim (I'm pretty sure it was the one below). At first I thought it was great that they actually acknowledged the impact she had on the land mind issue, but then I realized that they simply included the picture because everyone knows that any magazine that features a picture of Diana on it, sells.
