My big sister was at our Grandmére, who we call Grammy's house. Nothing more, nothing less. Grammy doesn't speak much English, so we talk to her in French. Grammy came here from France 2 years ago, to live near her child and grandchildren. Her house was spacious and beautiful, with a single rose on the side table, next to at least 20 books.

Grammy always liked that rose because of the fact that oddly it had never wilted. Mama gave her the rose as a welcome to America gift. She had always said that it looked like Mama's smile. She wiped a single tear off her wrinkly cheek and continued to read her book which in she had a considerable amount to go. It was late, so Sister went off to bed without saying anything.

Nice! I recommend adding a bit at the beginning , like them going to granny's house or the narrator seeing a picture of the sister!
