This one sticks out in my mind the most: The Brother™ who was Studying™ with my folks had a shop in town and the family went there. Other customers were in the shop. I walked up to the shop owner and very loudly said "What's up, Brother™?" having never been informed that it was inappropriate to address him that way in public, let alone at his place of business.
Well, I really got informed on the way home, followed by a spanking once we got home, for "embarrassing everyone".
I wondered to myself why anyone who knew The Truth™ would be "embarrassed" by being called Brother™ or Sister™, since that was how we were instructed to address adults at the Meetings™.
I was maybe 6 or 7 years old at the time.
