"Billy and Rose are back--and prone to serious discussion--in four charming stories about the ups and downs of negotiating friendship. Even best friends can disagree, whether the topic is books (tall blue books versus fat red ones), rain (will it or won't it?), the perils of a bad hair day (should Rose concur that Billy is having one?), or the incendiary question of which flavor of cupcake is best. Sharing--books and a purple umbrella, compliments and cupcakes (two flavors)--is the very antidote to seriousness in these stories." -- Publisher's description.
