In Good Day, Good Night by Margaret Wise Brown and illustrated by Loren Long, when the sun comes up and the day begins, the little bunny says good day to all the familiar things outside. To the birds in the skies and the bees in their hives, to everything one by one. And as the sun starts to set, it's time for the little bunny to say goodnight. Goodnight, kitty. Goodnight, bear. Goodnight, people everywhere.
