I seem to remember an article in the WT/Awake about traditions or something like that (sorry to be so vague) it was about 2 years ago...teeny tiny article. They said that certain traditions that at ONE time had been considered of pagan origin might no longer be considered BAD if they were not commonly associated with it's pagan/false religious origin. It used some foreign (aka not US) customs as examples...I believe it might have used throwing rice at weddings also. I will try to find this article and post it....
Anyway brought this up to some old-timer JW's and mentioned that this might eventually apply to B-days....they totally flipped out! lol could be the reason the borg are trying to slip it in very very slowly...
