It's sometimes a challenge to figure out exactly what Max has done during the day. We often have conversations like this:
Occasionnaly, little snippets of information slip out. This evening after dinner, in between sips of his blueberry shake, Max looked up and said, "Ella Fitzgerald was a great singer!"
(Well, sure, she was, but how do you know that?)
It sounds as if they learned about Ella in preschool today, and maybe did some singing ("we had a microphone!", says Max, "and tomorrow Christopher says he will bring two!").
