I NEVER took notes at any meeting or convention. God, it was torture enough just to have to hear it!
There was one devout sister in our congregation who took notes at every single public talk (and probably still does.) After every Sunday meeting, she would go home and type up her notes on a typewriter. She filed them in alphbetical order by the title of the talk. Because she was (is) still in the borg for so long, when they would announce the title of the upcoming public talk she already had notes on, she would go home and pull out her previous typed notes from the last time she heard it. She would bring that to the talk, make additional notes again. She would go home, retype it, adding in any new tidbits of info. Can you imagine putting that much effort in to every single Sunday public talk? And, by the way, she NEVER missed meetings, was always "prepared" (meaning studied, looked up every scripture, made notes in the margins of her WT).
