Describe personality

There are five people in my family. There are my father and mother, my sister, my grandma, and me.
Grandma is old, about eighty years of age. She is not very tall, about one hundred and fifty five centimetres. She is slim because she does not like to eat a lot. Her hair is white and her triangular face is wrinkled, but her eyes always twinkle when they look at you. When I am near her, I can smell a light scent of jasmine.
Grandma is a lovely person. She is nice to me and my sister. She never yells at us. She moves slowly because she has to be careful when walking. She does not talk a lot. She is a quiet person. However, she always tells us interesting stories before we go to bed.
