I downloaded the soundtrack so that we could all get involved on long car journeys. Funny, then, that on Sunday night, my husband and I started singing Love is an Open Door to each other as we brushed our teeth. Our daughter had been asleep for hours, so who were we doing it for? Had we bought the soundtrack for our pleasure rather than hers? When we found out that there was be a Frozen sequel, were our squeals of excitement for us or for our child? Could it be that we had enjoyed the film far more than she did?
