One day Lizette finds a pretty green sock. She's delighted, until some neighborhood bullies begin to tease her. Socks come in pairs, they say. What good is one sock by itself? Lizette searches and searches, but she cannot find the sock's missing mate. Fortunately, her friend Bert helps her see the situation in a new way. And together they come upon the perfect solution in this ingenious story about how socks, like friends, are always best in pairs.
