The nature of sadness. Michael Rosen’s Sad Book describes how sadness feels and tries to understand it. “Sometimes sad is very big. It’s everywhere. All over me.” Michael Rosen’s son, Eddie, died, and that, he tells us, is what makes him most sad.
“Sometimes I’m sad and I don’t know why. It’s just a cloud that comes along and covers me up.” Rosen asks these questions: Where is sad? When is sad? Who is sad?
How do we respond to sadness? The book examines whether memories can make us feel less sad. And does it help to know that sadness affects everyone?
