It all begins with a simple question posed by a patient mother when her impatient toddler shouts, 'I'm hungry ' 'What will you say when the doorbell rings and we open the door?' asks Mom.
'Hi, Pizza Man ' replies the thoughtful child.
(But) what if it's a pizza woman?.
a pizza kitty?.
a pizza duck?.
The book has a wonderfully satisfying roundness that comes full circle when the doorbell finally rings.
