the idea of the story was pretty good, a few spelling mistakes, probably just because it is rushed. I didn't quite understand the idea of belonging aside from just the memories of the grandma, maybe if you speculated on the whole orphan thing a little more? And not that my teacher is any good in my regards, but one thing she said that made sense is in short stories you should develop the characters quickly so the story can go on and what not. Might want to say something about her parents at the start to give her more attachment to the grandma? im in no way suited to give it a mark, but id probably go with a 10-11. Just my 2 cents.
hope it helps.
