Walking home from the library, a routine and normally uneventful stroll. Thomas is holding onto the left side of Mia's stroller, Darcy on the right. Suddenly musical Thomas bursts into song. Every line Thomas sings is echoed by Darcy: "I wuv Georgie!" carols Thomas. "I love Georgie," echoes Darcy. "He's my best boy." "He's my best boy." "Best in the world." "Best in the world." "I miss Georgie." "I miss Georgie." "Best boy inna world." etc. A paean! And antiphonal, to boot! Talk about Culture.
