Sample paragraph from my teacher - I don't know if this is what you mean:
Scrooge's existence on the edges of society is presented as a pitiable aspect of his character. Our greatest sense of pity is created in the line "A solitary child, neglected by his friends, is left there still." The lexical field of "solitary" links back to the elderly Scrooge being described with the simile "solitary as an oyster". This simile highlights Scrooge's distancing from society, locked in a shell and surrounded by a sea of misery. Scrooge's "neglect" by his "friends" could explain his later solitary life, and goes some way to explain his exclusion from society. Dickens wanted his audience to remember the fragility and vulnerability of a child, and, by using this imagery, Dickens has humanised the inhumanly cold Scrooge. What Scrooge suffered as a child is a reflection of the suffering of children at the time: loneliness, abandonment, and neglect. That we now pity Scrooge allows for the opportunity for Dickens' Victorian audience to recognise aspects of Scrooge within themselves, and forgive themselves on the path to redemption. Once Scrooge finally learns how pitiful he is, stating his "life tends that way, now", he learns to pity others.
I would appreciate some Macbeth analysis please.
