I absolutely detested the watchtower study. Never did an hour go by so slow. There would the 20 or so paragraphs that had to read and answered, and I would watch the clock. As it neared an hour, sometimes I would get excited knowing that it was almost over, but sometimes they were still on paragraph 15. Did they stop on time? No! Of course they had to finish, even if that meant going overtime by 5, 10 or 15 minutes. That was truly hell.
Going out in service was horrible too. Especially as a kid, and if you were working the neighborhood you lived in, or went to school. The idea of running into friends terrified me.
And then, being a kid, dressed in a suit, having to hang with your parents after the meeting or service, going off to run errands or something, and having to wear that suit the whole time, having people make weird looks. You just don't normally see kids in suits and dresses out shopping.
