In order, worst first ;-
Elders Meetings, they happened in MY time ! extra to the 5 meetings. My heart sank when the PO asked for "Five minutes" after the Thursday meeting.
Service Meetings, How can you make an item interesting when it is the same as the one they heard every week since Rutherford died? and you were not supposed to depart from KM hardly at all....snoozeville to listen to...
Public Talks .. For the reasons everyone has said already. Unless I was delivering it of course
Watchtower Study .. Cruise through the first 2 or 3 paragraphs, make a comment then dream through the next 10 paras, comment again , then look forward to lunch and dream to the end
Group Study. Although it varied. A lively bunch, a decent conductor and some half interesting material would be ok . Too often the conductor stifled rather than provoked discussion so few said much . At least it only took an hour.
Theo School. Not too bad. Each segment was brief enough to be not boring. A lot of it was not done by elders so at least they were decent people for whom one felt a kinship and you wished them well. And it was mostly scriptural
All in all, I would rather spend Meeting nights posting on JWD...
