One of the things that liars do, apparently (I researched this when I was married to one) is waffle about a number of minor details in order to seem honest and open, but in actual fact avoiding the main issues/questions.
So PA waffled over the sweating, and over the Pizza Party and going to Woking, and went into great detail.
He reminded me of Bill Clinton who was unable to say Monica Lewinsky's name so he said "I did not have intercourse with that woman" - thereby also nitpicking between "intercourse" and "oral sex".
And PA would only say that he had "no recollection" about almost everyone and everything.
What I do wonder about is .... if he was lying all the way through that interview, why not condemn Epstein and his friendship with him, even if he didn't really feel it? If he is lying about other things, why then defend his friendship and try to justify it by saying he "learnt a number of things" (I bet he did!) and not come out and say he deeply regretted ever knowing the man! Why not get lie and get himself off the hook?
