Regarding cognitive dissonance - while in the process of extricating myself from TWI in 1988, I experienced a strange process going on in my mind. I was starting to think original thoughts - thoughts that were contrary to my TWI programmed thoughts. Sometimes I would hear Craig yelling against my thoughts, yelling things I had heard at mealtimes in residence.
So I did the thing with the line down the middle of the page. Left side - my thought, right side - TWI rebuttal. Back and forth, back and forth. Like having two brains. As time went by, my own thoughts predominated and the yelling rebuttals receded.
Many years later, my brain belongs to me. And TWI is a distant far off strange thing I was in....... the farther back in time it gets, the stranger it seems.
