I just recall that they were long and boring. The best thing you (a brother) could hope for was to get an "assignment" that required you to be "working" during the sessions. Auditing was good, or being an attendant in the hallways telling others to find their seat. Even better was being a "big shot" in the Chairman's Office or Administration where you got to rub shoulders with all the Bigwigs from Bethel.
It does seem like many former JWs still have that problem with "long & boring" when they make their YouTube videos. I guess it just stays with a person.
