I have a DCG that introduced me to Frozen music (from the movie, Frozen!). She came in one day raving about Elsa (who I at first guessed was an imaginary friend? I've been wondering when one of those would show up, this girl has a huge imagination).
She's about to turn four and all she wants in the whole world is an Elsa party! I really need to watch that movie. Sounds like you had a nice afternoon!!
