Scrooge sat in his counting house day after day, he "carried his own low temperature always about with him; he iced his office in the dog-days" (Dickens, 621). Scrooge carried his misery with him, showed no generosity, and no love for others.
Fred is one of the happiest characters in the story, he shows generosity and love for everyone. When asked why he was merry, he told Scrooge that he was in love. Fred goes to Scrooge "in good temper, year after year, and [says] 'Uncle Scrooge, how are you?'" (Dickens, 652).He shows Scrooge kindness every year because of the good in his heart.
During Bob Cratchit's Christmas feast he said "'I'll give you Mr. Scrooge, the Founder of the Feast!'" (Dickens, 649). Even though Scrooge was cruel, and gave him poor working conditions, Bob still found it in his heart to thank him. He didn't need to thank Scrooge, but he still did, and that's out of the love in his heart.
After Scrooge's realization that he need to be more generous and loving, he went to Fred's house, Fred was very happy to see him. When Scrooge got there "it [was] a mercy he didn't shake his arm off." (Dickens, 668). Fred forgot all the remarks Scrooge had made about him, and all the bad things he's done because he saw Scrooge making an effort.
