in a christmas carol, dickens shows that a loving family provides companionship, support and strength, even in difficult times
the cratchits exemplify the theme of family in the novella: although they are poor, they love each other, find joy in each other's company and look after each other in their hardest moments
dickens presents family as bringing a level of happiness that no amount of money could buy
scrooge is alone at the start of the novella, but dickens makes it clear that this is his own choice - he has his nephew, fred, but rejects the chance to have a relationship with him
scrooge is bitter about the neglect he suffered from his own father and the chance of a family of his own that he lost when belle broke up with himd
dickens shows that scrooge's bitterness about the past holds him back from the chance of happiness in the future
when scrooge finally accepts fred's dinner invitation and opens his heart to the cratchits, scrooge finally experiences all the joy of a loving family that he rejected for years
dickens also shows that family relationships last for a lifetime and that it's never too late to patch things up with a family member
fred never stops showing scrooge love, even though he's constantly rejected, and when scrooge finally realises the error of his ways, fred shows him unconditional forgiveness
