hey believe his lies because he explains everything so deeply. When he went to Ms. Havismam's, it didnt go exactly how he wanted it to. It was awkard and he didnt like it. But he couldnt tell Mrs and Mr Joe and Uncle Pumblecook that. He had to lie. At first Pip just said that it went pretty well. Pumblecook did not like that answer at all. He wanted to know exactly what happened, but Pip did not want them to know the truth. So, he lied and made up things that happened and made up things that were in Ms.Havisham's house. They believed his lies because uncle pumblecook wanted to go inside Ms. Havisham's house, but he was not allowed to. Since he was not allowed, no one else knew the truth about that was inside, so the only person they could count on was Pip. They had no other choice but to ask him, and of course they believed him because did not know that he was full of lies.

entence: He was a secret-looking man whom I had never seen before.

Explanation: He was a secret-looking man whom I had never seen before. This sentence is when Pip is with Joe at a bar at the Jolly Bargemen. Joe was smoking his pipe in company with Mr. Wopsle and a stranger. Joe greeted me as usual and the moment he said that, the stranger turned his head and looked at me. The stranger had his head on one side, one of his eyes were half shut just like if he had an invisible gun in his hand and is trying to aim it, had a pipe in his mouth and took it out [blowing smoke out of his mouth] and after that looked at me with a look and just nodded so then I decided to nod my head back at him which then he also decided to return a nod back to mine. He wore a flapping broad-brimmed hat and it a handkerchief under it that tied over his head in the manner of a cap so that he showed no hair. As he looked at the fire, I thought I saw a cunning expression, followed by a half-laugh, come into his face.

Well first of all Pip was extremely over doing it with his lie about his visit to Miss Havisham's home. As to their actually believing him well Dickens apparently has a sense of humor. Dickens likes to exaggerate in his stories I've heard from my teacher Mr.Bar so I assume that in this case that is what he is doing.  I'll summarize his more than tall tale up a bit. He told them she has a coach in her room and has 4 large dogs. (At that time to own a dog was to mean your were wealthy enough to support yourself and some other thing so four dogs of course is extremely questionable.) He also made note that they played with flags and swords. Quite ridiculous but his sister and Pumblechook, or otherwise his antagonizers, took it in disbelieving agreement of it being the truth because neither of them had been in the house before which was extremely bizarre for Pumblechook because she is the one who had the duty to bring Pip. In fact the he had only seen or talked to her through a slightly ajar door. Pip actually sort of played on that knowledge to advance his lies credibility whether it was luck or coincidence only Dickens could know. Pip had said there was no daylight in the room but instead it was lit by candles and then Pumblechook, I like to hear the sound of my voice, jumps in and exclaims that statement to be true that much of the case he had seen himself. Their gullibility Pumblechook and Pip's sister  was like said extremely exaggerated by our lovely author Dickens and this through him Pip was aloud his comical scene of childhood imagination. In short Pip's sister and Pumblechook are stupid butt holes.
