RAH! RAH! RAH!
(we are big boosters of our author and illustrator peeps)
Alexander doesn't remember, of course, but Adam read me the manuscript of his FIRST amazing-incredible-silly-fun book, whilst sitting on the rug in the then-nursery.
Adam was also the first person to read me the first Mo Willems Pigeon book, and it is his quasi-Spanish/Italian-German/Yiddish* voice for the Pigeon that I employ (to the best of my limited abilities) to this day when reading to children.
*before I had ever seen an episode of "Phineas and Ferb," a girl in Ander's first grade class told me that my version of Adam's-Pigeon-voice was very very close to the voice of Dr. Doofenshmirtz. So there you go.
