I've done some soul-searching on this thread, and for me it was three things.
I liked that total sense of acceptance when I had prepared completely for a "study" (ha ha) and I was all underlined and highlighted in my Watchtower or bookstudy book and I put my hand up to answer and I heard my own voice giving the answer in my own unique words over the sound system and then I was told "Excellent answer, sister."
Do psychologists have a word for that? Oh yes, self-brainwashing combined with liking the sound of your own voice.
And then I liked it very much when I was sitting next to a cute guy I liked. That happened a few times. We were so "spiritual" together.
I think I know the words for that. Sexual attraction.
Then also, waiting to see where everyone was going for milkshakes or burgers, and once we were older, for drinks, after the meeting, and whether I'd be invited again tonight. Or whether I should make a plan and do the inviting, just in case.
That was pure teen socialization.
