It's so hard to choose, but I would have to say the theocratic ministry school was my most hated meeting. The first few talks were a rephrasing of mind-numbing society doctrine. Then it was time to listen to a ten-year old read NWT to us........... #3 talks, don't even get me started! The #4 was the highlight for me. Time to wake up and get ready to stand (if I'm able) and sing a sawng of praise. Yay.
It was a well planned program, because without the song-n-stretch no one would make it through the announcements awake. I'll have to search for it, but someone has a whole service meeting (with multi-page letter from Bethel!!!!!) audio for download. If you haven't been to a meeting for a while, it's an amazing experience. It's hard to believe you actually sat through this stifling boredom, some of us for years!
I'd love to hear what your least favorite meetings are/were, and why.
