Suddenly, Granny Lida

Vasya suddenly acquired a grandmother. You might ask: how is she sudden? Easily! Vasya came home from school, and on the sofa in the room sat an unfamiliar old woman, knitting a striped sock, who introduced herself as a distant relative. That's how they met.
But that's not all. Grandma Lida didn't come to Vasya's house alone, but with her goat, Mashka. And so, a new life began for Vasya – sudden and joyful.
