Chairman of our JC inadvertently mentioned someones name to me on the phone ( a friend of ours, elder PO in a nearby cong) who he had been gossiping with about our apostasy. Then corrected himself really obviously - I let it slide as I was pissing myself laughing at the time with one hand over the mouthpiece as I couldn't find the mute button.
I knew he had been talking to this other PO about us as the PO's wife told us.
