This is yet another one of those “twin” things that I am constantly amazed by. Unplanned synchronicity. Lucy is working on her sticker book. Zoe, sitting nearby, is working on her sticker book. One of them starts singing. The other joins in. They continue for like 30 minutes or 42 hours, I’m not sure which. Together. Without looking up once, and with no discussion of any singing game plan. To sing. That’s the unspoken plan. In unison, in succession, loudly, quietly. Whatever — just sing.
