Max has been doing a lot of pretend play lately, and it's fascinating. But as I watched him on the phone the other day, I wondered: Who was he pretending to talk with? What made him crack up like that? At times like these, I long to know what is going on inside his head; it makes me wistful that I can't be in on his joke. Especially when Sabrina's right there prattling on. Then again, it also makes me happy to see Max talking like he does and expressing himself.
