Heres a list:
(1) The sound of kids getting spanked; it was so loud you could hear it at the front of the hall when they were getting whipped in the back.
(2) The false kindness. Anyone that was inactive for a bit before they left should know how this feels. The people that would not acknowledge you outside the hall, because you were 'bad association', would give you a little cold and tight lipped smile when you showed up to the meeting hall.
(3) The formal dress attire. I always thought it was pointless; it makes more sense to dress for comfort and not for show.
(4) The length and consistancy of the meetings. All the information in a 2 hour Sunday meeting could have been delivered in 30 minutes or less.
(5) The politics of the collective. Grown adults getting upset because they were not called on to answer a question.
Jelly (Just the first five that came to mind)
