Рассказ на британском языке о родственнике

I want to tell you about my grandmother. Her name is Anna. She is 64 years old. My granny wears short dark hair. She has strait nose and green eyes. When she was young was very beautiful, slim but when she became older she became fatter. She used to work at the shopping center as a seller but now she is retired. She is very kind! It is one of the most great trait. She spent a lot of time with the grandchildren they were young. She is always ready to help. By the way, she is the best cook I know!
