After pulling Mago’s tooth out, I floss him for bed time. I look in his mouth and make a puzzled face. He sees this, and starts to be amused.
“Wait a minute”, I say.
He starts to giggle.
“Wait five minutes! Something is different!…”
He’s giggles more.
“Wait an HOUR!”
He laughs a lot.
Over the next few days he says to me at random times: “Wait an HOUR!” – and laughs.
