My Grandfather's Little Shop

A lively, clever, and very inventive girl decides to help her grandfather in the grocery store.
The young inventor eagerly gets to work. She records the poor people's purchases in a debt book on wealthy visitors, takes sweets from friends to give to hungry children. However, Grandpa is not thrilled with her ideas! He just grumbles and holds his head. Why are these adults always dissatisfied with everything?
The restless heroine has to understand why it’s so difficult for adults and children to hear and understand each other and, despite everything, find her way in life.
