Grandma said to sit quietly

Grandma Zoya lives alone, but she regularly bakes pies for someone and glances at the cupboard.

The neighbors, with whom she occasionally goes to the forest for mushrooms and berries, suspect that their friend has gone a little crazy from loneliness and believes in the existence of a house spirit.

But there is indeed someone living in the cupboard. Someone fuzzy, who cannot talk, has never left the house, and has never seen the sky.
