Ha ha ha - I'm too stupid fer the big stuff, but I think I agree with you.
I'd say this guy is just full of himself and likes to play with words - and
since no one can understand a damn thing he's saying - they aren't likely
to refute his position. His resume proves to the world he is an EXPERT!
I think this is his only point. ha ha ha
On the other hand - it may all be true - or false - or real - or not.

I think I'd skip to the last chapter just to see how he ends it.
Then you can go play with your new sewing machine ( which is real) and has
definite meaning to you - and chunck ol Barrow in the insignificant pile
that you can always refer to for "party chatter" should you ever be
desperate for nothing meaningful to say. ha ha ha ha

love,
alice
