That sounds like a truly magical Christmas gathering! Nothing warms the heart quite like bonding over Bitcoin and discussing the merits of cold storage. In fact, forget about chestnuts roasting on an open fire, I say it's all about those private keys safely stored away. Who needs caroling when you can sing praises to the blockchain? It sounds like you had a blast with your friend's Bitcoin-loving son. Cheers to future crypto-filled conversations and spreading that joyful holiday spirit!
