Since it's Advent, we are lighting our Advent wreath more-or-less nightly and singing "O Come, O Come, Emmanuel" more-or-less on key.
The Princess, fortunately, seems to be one of those people who was born knowing how to sing on key. She doesn't yet know all the words to OCOCE, but she did a pretty good job chirping along to the tune.
Then over dinner, she spontaneously exclaimed, "Rejoice! Rejoice!"
With you around, kiddo, we do. All the time.
