I witnessed something years ago that I've always wondered about and would like eHell's opinion.
I used to attend a small church, and during one service they had a little "graduation" ceremony for the kids who were in the children's class (like Sunday School, I guess, although we didn't observe the Sabbath on Sundays.) The announcer called out the kids' names, they walked the stage and got a certificate and we applauded each one and it was a cute little event.
Tragically, a few weeks before one of the women in the church had been killed in an auto accident. She had been involved in the children's class and the announcer started talking about her. She had been a good friend of his and the poor guy lost it and started crying there on stage; I don't even remember if he was able to finish the memorial-type text he was reading.
Of course I felt terrible for him and all the deceased woman's friends and family, but at the same time I felt bad for the children: their achievement had been eclipsed and the celebratory mood had been turned on its head; and, as I recall, the ceremony ended on this sad note.
So, eHell, I'm torn. On the one hand it would seem rude to not acknowledge the late woman's work with the children; on the other hand it also seemed rude to shift the focus off the children themselves. I'm also sure the announcer didn't intend to break down like that.
On a similar note, when I was a child a younger relative of mine died on my 10th birthday; it was the first "big" death in my life and I was devastated, but it seemed like every year my dad would go out of his way to bring it up to me on my birthday. Yes, I do feel horribly selfish admitting it bothered me. As an adult I'm now somewhat glad of the timing, because I will always remember to call or send flowers to her mom and let her know I'm thinking about her, but looking back I'm not sure why my dad would bring it up as much as he did (I don't recall him ever mentioning the anniversary of anybody else's death to me.)
