The speaker, introduced as George, appears to be in denial about the cause of the expectations surrounding 1975. He and his family have huge sunk costs. He has been employed at wt for 42 years and at age 60 or so he has few other job prospects and likely no way to support himself in retirement. His employer made up this stuff about 1975 and pushed it hard. If he blames them, he loses his livelihood.
My impression is that this is type of self flagellation, or, to use a communist era term, "self criticism". Instead of admitting he was duped by Freddy and wt, he takes the blame upon himself, and brags that he was able to get over it by keeping it in his head and not letting it go to his own treacherous heart. It's what he needs to do to feel good about an awful situation. Or maybe he suffers from folie a deux. Any jw under 60 will take him at his word, if they are still asleep. Older ones will try hard to agree with him.
