It was a rainy day in the end of summer and grandma Ruth got a letter. It was from Harald and he was wondering if grandma and her granddaughter Rosita could take care of Margit, his cow, for a couple of weeks. When you are going to take care of a cow there is so much to do. The cow has to have a pasture to walk and eat in, somewhere to be protected when it rains. Its a lot of work but, oh how much fun it will be, grandma Ruth and Rosita thought. And it was fun and nothing like they thought it would be because Margit is not like all other cows...
