Christmas Carol Scene SignificanceWatch
The next scene is of a lighthouse and the setting is described using adjectives with a semantic field of old age and desolation. It is a "solitary lighthouse" which I believe is a comparison to Scrooge's childhood. Once again, these men have "light" from a "fire" and are celebrating Christmas together. Finally, Scrooge is taken to see some men on a boat and although they are "ghostly figures", they are humming Christmas songs and remembering those who they "care for".
All of these people are alone in some respect but they all are celebrating the company of others. I believe that each of these scenes are shown to remind Scrooge of the things he was shown by the Ghost of Christmas Past. Scrooge was lonely when he was younger but even when he had the chance to integrate himself into society, he chose not to do so. These people would do so in an instant if they could. This is a lesson from the Ghost of Christmas Present that it is not our situation in life that determines our identity, it is the people we are surrounded by and ourselves that truly have the biggest influence on our attitudes. It also shows Scrooge that he must use the lessons of Christmas Past in conjunction with the present to make the best of the future.
This is simply my response to the inclusion of those scenes and I hope that it gives you a few ideas! Also, apologies for any mistakes- I wrote it very quickly because my first answer got deleted :/
