Remember the born in JWs were raised looking over their shoulders. Even perceptions of misdeeds could result in a JC , reproof, disfellowshiping, marking, humiliation or reflect badly on JWs or your family.
Appearances were the most important thing, not the reality. Most JWs grew up with the "no reproach on Jehovahs or his Org. name"mantra. Can you imagine the pressure it puts on a child? You learn what is appropriate and when. You learn to lead a double life and justify what you do.
You have watched adults all around you say one thing and do another in private.
It becomes second nature, instinctual to always keep good appearances .If you look good, God looks good and your family looks good. Everyone is judging you.
My elder dad, was physically ,emotionly, and sexually abusing us. The worse beating of my life was because he thought i lied to him because i didnt say what he wanted to hear. It didnt matter that we were living a lie. Or that he was having us lie for him.
Most JWs are living some sort of lie. You just caught your JW and refuse to accept his lies. Most of us usually expect it in some way. Iying is the only way to survive
I am curious as to what kind of home life he had. I bet he had to jump hoops to get approval from his parents and everything he did was never good enough.
