I can't tell you how angry I am right now. My utterances are ineffable. How am I supposed to illustrate a picture book that doesn't have any words in it? Oh, wait a minute. Here is one. Honk.
Oh, make that three. Honk honk honk. How am I supposed to know if they want a car or a goose?
Cars beep. Geese honk. And so do blowing noses. But if you don't believe me you can always ask the writer what he has in mind.
