I remember attending one as an MS. I was the only one in a cong. with about 7 elders. It was pretty much like any other meeting with scriptures read and a few comments asked for. We met in the POs house and sat around a big dining table. The CO would get us to read the scriptures that came up in the outline in turn. (At this point I should say I had a goatee beard. Things are a little more relaxed about that in Ireland - depends on the cong. But you still can't have one on the assembly, go figure!)
Anyhoo. The society seemed to want to clamp down on tattoos and there was about 10 minutes of his meeting devoted to the subject of what to do if someone in the congregations turns up with a tattoo. Anyway it was my turn to read the scripture. "Brother, would you mind reading Leviticus 19 verse 28?" said the CO. "Sure" I said, "So long as I can read the verse before it too!"
I think this went way over the heads of most of the old crusties at the table, but one elder who I used to be close to gave me a knowing look. Yeah I'm pretty sure he has a brain hiding there somewhere. Anyway, score one for me, I was such a rebel. (A bit of self parody here, but it was one of the few times when I felt like saying something and actually summoned up the courage to do so)
