Estella is very cruel towards him, "what coarse hands he has". Dickens chooses the word "coarse" being quite blunt and straight to the point word. Estella does not beat around the bush in telling Pip what she thinks of him. She treats him as if he was inferior "he is a common labouring boy!" .He is very insulted, upset and embarrassed at all of this and when he is given food as if he were a dog in the yard he is overcome by anger and is so insulted he violently kicks the walls and cries.
After this visit to the surreal house he begins to feel ashamed of what he is and he even feels ashamed of Joe, who he has looked up to all his life. He lies to his family about what he did there and he feels guilty for it. He confides in Joe after about it all and Joe states that lying is wrong. Pip feels it very easy to lie and when he lies about what he did at Miss. Havisham's it almost seems to slip out without him meaning it to. He has begun to find it much easier lying than telling the truth.
Pip becomes "disgusted with his calling" he is ashamed of his home, future and life. He had once been proud and looked forward to his future but "now it was all coarse and common" Estella has made him become very unhappy and believes that everything in his life is, as she said, common and unworthy. He had once enjoyed his life and was happy to be partially uneducated but Estella's words have altered that. He now starts to wish that he had been brought up better, not in a blacksmith's forge but in a civilised society.
Pip wants to "be a gentleman", to be well-spoken, well dressed, educated, not coarse and not in any way common, "Biddy", said I after binding her to secrecy, "I want to be a gentleman". At this point Pip chooses to confide in Biddy and not in Joe as he always did. Maybe this is because as Joe is uneducated Pip thinks he would not understand. We also become aware that he is disgusted with his calling and explains an alternative life where he would not be disgusted with his calling.
