The Elves and the Shoemaker

One sunny morning, the Shoemaker and his wife got up and had a cup of tea before a hard day’s work. The Shoe Maker was tall and had grey hair. He had brown spotty glasses and was wearing overalls. His name was Jonathan. Mrs Shoemaker was tall and had dark brown hair and bright pink glasses. She was wearing a daggy old brown dress. Her name was Rosina. Then, suddenly, there was a knock on the door.
