I agree with slim and SouthCentral advising those who are unsure to attend a funeral if the deceased meant something to you. It's a chance to pay your last respects and you may regret it forever after if you don't go.
I zoom attended a very large memorial earlier in the year. I was super close to the family for years, and my JW family bent over backwards to make me aware of the memorial. It wasn't too bad and I'm not sorry I "attended" for the reason above.
On the other end of the spectrum, Aude and I attended a KH memorial a month ago for a relative of another poster from here. She said she could use the support and we were there for her. OMGoodness, it was truly a DREADFUL talk. Just dreadful.
Dagney, you've raised an interesting question. It's curious that given how important funeral talks are (and by the nature of things, how often they have to be held), there seems to be such variety in the quality of them. Especially when you think how tightly the org controls the content and tone of every other meeting.
Like you, I've been to some funeral talks that have been excellent - well-balanced and respectful, with enough time in the talk and information in the programme devoted to the individual and their life, not just a commercial for JWdom. On the other hand, I've also been at the two bad types of funeral talk: 1) out-of-the-box generic advert for JW life and the org with little mention of the deceased, and 2) dull as ditchwater coverage of the funeral basics from a speaker who clearly knew nothing about the person they are talking about.
Isn't it odd that there is such a wide difference when the org usually controls all other talks so tightly? Admittedly, if they were to tighten up how funeral talks are delivered, they'd probably end up making them ALL like the two bad examples above, so I suppose I should be glad they haven't done that. But on reflection, it seems strange.
