This Caldecott Honor classic is a simple yet important story about friendship.Two kids meet on a street. "Yo!" says one. "Yes?" says the other. And so begins a conversation that turns strangers into friends. With vibrant illustrations, Chris Raschka's rhythmic read-aloud is a celebration of differences -- and how it just takes a few words to overcome them. More relevant than ever in our divided world, this 1993 Caldecott Award-winning classic is presented for the first time in a board book format.
