Final answer:
Scrooge initially treats his nephew coldly and dismissively in 'A Christmas Carol.' Over the course of the story, after being visited by ghosts, he becomes more warm-hearted and ends up celebrating Christmas with his nephew, signifying his transformation.
Step-by-step explanation:
How Scrooge interacts with his nephew is central to Charles Dickens' 'A Christmas Carol.' Scrooge, who is initially a miserly character, shows a cold and disdainful attitude towards his nephew. His nephew, on the other hand, embodies the spirit of Christmas, being cheerful and optimistic even in the face of his uncle's miserliness. The nephew invites Scrooge to Christmas dinner, an invitation which Scrooge dismissively rejects.
Over the course of the story, following visits from various ghosts, Scrooge's attitude toward his nephew changes significantly. By the end of the tale, Scrooge becomes more open-hearted and generous, joining his nephew's Christmas celebration and mending their strained relationship.
