Knowledge is power. Some people with knowledge others don't have love to flaunt their "insider" status. It's a power trip.
My elder father had strict rules about the privacy of his meeting bag, desk, and any phone calls he received. If we answered the phone we weren't allowed to ask who was calling. I got used to that, so when I got married and my husband became an elder I didn't ask or snoop. If I came across confidential info accidentally I kept it to myself out of loyalty to Jehovah. I was waaaaay serious.
All the same, in later years my father loved to come out of his study and drop a few hints that he knew something we didn't know - something BIG.
Can you hear my eyeballs rolling?
