When Scrooge meets the Ghost of Christmas Yet to Come, he bends "down upon his knee” before the Ghost - seems to get lower every time he meets the Ghosts. This could link into the idea that every time they visit him, they show him things which make him feel more lowly and regretful
Showing Scrooge's ignorance of the city and society in which he lives, Dickens tells us how Scrooge and the Ghost enter a part of London where “Scrooge had never penetrated before, although he recognised its situation, and its bad repute”
Scrooge hears how badly other people think of him – in reality, it is doubtful that anyone has ever told them what they think about him to his face
Scrooge sees how his wealth will not save him, or be useful to him after death - Ghost shows Scrooge that nobody will be sad when he dies - "Let me see some tenderness connected with a death” - he wants someone to have cared about him.
“He was very light to carry… and his father loved him so.” - past tense shows that something has happened to him. This is incredibly upsetting to Scrooge, and to the reader
“I am not the man I was. I will not be the man I must have been.” - Scrooge vows to learn his lesson and change, to be a better man and a kinder person.
