Interesting point, Jonathan, about Pip's metaphors..
You say: "the brewery beyond, stood open, empty and disused. The cold wind seemed to blow colder there, than outside the gate; and it made a shrill noise in howling in and out at the open sides of the brewery, like the noise of wind in the rigging of a ship at sea.'
How could he know that? It was thiry years later that he crossed the ocean to America with the wind blowing a gale."
JoanP, what you say about the stories that Pip told about Satis House makes sense: "I think he came home with the lies - protect Joe and his sister from his real feelings about them."
What you say, PatH, makes sense too: "I think Pip was totally overwhelmed by his first visit. The whole setup was so strange. On top of that, he is humiliated, made to feel that everything about himself is coarse and despicable, made to feel ashamed of his home. He doesn't know what to make of it, needs time to process it all, certainly doesn't want to share his feelings with unsympathetic adults. But he isn't given this time, he's badgered into telling about it. It's a defensive mechanism to clam up about what really happened and to lie."
It's believable to me that Pumblechook has never stepped in the house and has never seen Miss Havisham.
Dickens description of Miss Havisham is out of a fairy tale. It's not very believable that she would wear the wedding clothes day and night, including the one shoe, and that there would be much material left.
