In Pearl S. Buck's Christmas Stories, we might find characters who are outsiders or immigrants. Given Buck's interest in different cultures, these characters could bring their own unique perspectives on Christmas. They may be trying to adapt to a new way of celebrating Christmas while still holding onto their own cultural traditions. This would add an interesting layer of complexity to the stories as they interact with the local community during the Christmas season.
I imagine there would be some community figures like the local pastor or an elderly neighbor. The pastor could be spreading the religious and moral messages associated with Christmas, while the elderly neighbor might be sharing stories of Christmases past, adding a sense of history and wisdom to the stories. There could also be poor or needy characters, for whom Christmas might bring a glimmer of hope or a chance for a better life through the kindness of others.
