“I think it’s Carole King’s ”Tapestry” on the record player. But which song? ”It’s Too Late” would make thematic sense – my dad’s smile has the let’s-just-get-through-this tension of a code-red marriage.”

I understand that they the Smith family was so used to their own traditions and nothing else made sense. They were listening to a song that represented this “theme” or their Christmas.
