What was Scrooges behaviour towards his nephew in "A Christmas Carol"?

I think what
is important to remember about the way Scrooge acts toward his nephew is that in the beginning
of the story, he is in his own world, not realizing necessarily how harshly he comes across to
other people, including family members.  Because of this, he acts unkindly toward his nephew. 

Throughout , however, Scrooge is visited by a series of spirits: Christmases
past, present and future. These spirits show him how his actions have affected him and the
people around him, and how they will continue to affect those people.  What particularly pains
Scrooge and prompts a turn around is when he sees his nephew in Christmases present and future
not speaking kindly of him with his friends, and not remembering him fondly in the future.  He
decides at this point that he wants his family to remember him fondly, and this includes acting
much more kindly toward his nephew.
