Well, he wanted something and wouldn't say, so I got the book. He carefully paged through all the pages. On the last page, he smiled and picked "Pink." Then, he repeated out loud: "I want Pink."
I realized he wanted a pink Gogurt, so I went and got one.
Then, he came back and asked for chips. I said no because he had already had some. He looked through the book. He found "Yes". He put it on the card and announced: "I want 'Yes'!"
