As JWs we were pretty isolated. There were a lot of things I didn't know about the larger world; a lot of expressions I had never heard. The one that probably embarrassed me the most was:
when the shit hit the fan
I was in a business meeting and I was definitely low man on the totem pole. Well my boss used the expression and my head went into a pretty vivid image of this happening and I could not stop laughing. After trying to stop I finally had to get up and leave. No one mentioned it to me later so I have no idea what the other thought but I hope they were glad I got up and left.
I never led a double life as a JW. I stayed home to rais ethe children so had very little contact outside the JWs. So I had a lot to learn when I left.
I know there were other things but that was the worst for me.
So are there things you didn't know? Wished you had known? Embarrassed the hell out of you?
