QUOTE : Kästner was one reason I called my book barge the Literary Apothecary,” said Perdu. “I wanted to treat feelings that are not recognized as afflictions and are never diagnosed by doctors. All those little feelings and emotions no therapist is interested in, because they are apparently too minor and intangible. The feeling that washes over you when another summer nears its end. Or when you recognize that you haven’t got your whole life left to find out where you belong. Or the slight sense of grief when a friendship doesn’t develop as you thought, and you have to continue your search for a lifelong companion. Or those birthday morning blues. Nostalgia for the air of your childhood. Things like that.
