Bizzare in a wonderful way, this could be a metaphor or...it could not be. Maybe its about depression, but maybe its just about a strange magical house where it rains indoors! If it is about depression, then the gentle message seems to be that having friends and community makes things better, which is a solid moral. But on the whole, this book is not terribly moralizing, and invites oyu to enjoy it just as it is: a strange little story without need for subtext.
