Granny has lived alone for a long time now. It's been over two years since grandpa vanished on a bright autumn day on his way to pick mushrooms. Hope for finding grandpa has been fading and granny has gotten over the worst sadness. However, today she's been particularly sorrowful. She found an old advent calendar from her Christmas decoration box. It was made by grandpa and it brought up all the good memories. Granny sat on her rocking chair holding the advent calendar when she heard a knock on the door. Who can it be? Granny isn't expecting any visitors. What a surprise there is behind the door. Granny almost had an heart attack. What an earth?! Grandpa! Where have you been???
