Skin, to answer your question, when I attended a few meetings back in February, there were two other women near my age who had returned after 20-30 years away. All of us were in the 55-70 age bracket.
I was going thru a marital separation and was very vulnerable. My mom convinced me to go back.
Sister #2 was back after being gone many years. She was discouraged already, and sighed, "Well, where else do we go?"
Sister #3 was about 70 years old. Her husband had just passed away, and she was a lonely and vulnerable widow lady. She said she'd been away for 35 years, but was looking for meaning, so she came back to the Hall. She was really on board with her tablet and clicking the links to the scriptures during the clam. I really liked her. Sadly, I couldn't tell her why I quit coming because she'd be obligated to report it to the elders. I'd have liked to stay friends with her, but I couldn't tell her the truth.
I don't know about the other two, but I didn't stay long. It was the same old baloney as I left, no, even worse. After the life crisis passes, I suspect the fog clears and the "returning ones" probably drift away.
