i would like to tell you a story about my granny.She's really the most fantastic old lady in the world!Her real name is Marceline, but i call her granny Marcel ! Before she moved to the city, she lived in the country. Round her nice farmhouse there was green grass and beautiful flowers.Granny Marcel lived alone in her house.My parents and i could not visit her very often.So i was always so happy to spend my summer holidays in granny is house Granny Marcel didn't feel lonely because she had so many animals to take care of: a cow,five, hens ,two sheep and a cat.But one day Granny Marcel fell ill.She was not very seriously ill but my father said to her: "you should move into the city and agreed with us."Granny Marcel thought about it and agreed with my dad."All right !"she said suddenly."I`ll move to the city".It was very difficult for her to say goodbye to her animals.But the kind people from the next farm over promised to take care of them.Aften jist a few days granny Marcel wasn't too happy in the city in our flat.One day she went to our balcony .It was big and got a lot of sun.She liked it very much and decided to grow some flowers there.But soon she looked very unhappy again."Are you missing your animals,granny?"She nodded."Why don`t you go to the country and bring them all back here?"I suggested.And granny Marcel smiled.She came back in a day or two with her cat,five hens and a sheep.I helped her to feed them all and get them onto the balcony.Nowadays granny Marcel is much happier with her flowers and her animals on the balcony.But there is still one question:"How is she going to get her cow into the flat?"
