Narcissa, who was a master of small talk in the magical world, had been at a loss for conversation topics suitable for Muggles. She spent weeks leading up to Christmas exchanging owls with Severus about appropriate conversation topics.  Draco had also spent time researching, picking Harry’s brain about Muggles and Christmas. If Hermione knew how hard they had studied she never let on, she had however fallen even more in love with Draco as a result of the wonderful Christmas day they had shared.
