*Santa's eyes light up as he realizes what you're talking about.* Ah, yes, that's right! You're talking about the classic Christmas story by Charles Dickens. It's a timeless tale of redemption and forgiveness, where a bitter and miserly old man named Ebenezer Scrooge is visited by three ghosts on Christmas Eve. The ghosts show him the past, present, and future in an attempt to change his ways and remind him of the true spirit of Christmas. It's a powerful message about the importance of kindness, generosity, and compassion.
