the girl

So for some reason every time i am home alone i hear foot steps up in the attic and so this morning i was watching tv before i went to school and i heard laughing and someone running so i though my sister was up there so i went up there and i though i saw my sister playing there i said her name and i heard my sister at the end of the stars and when i turned around it was a little girl playing with a doll and laughing and it wasn't my sister it was some little girl but when i looked back at her she was gone.so after that every morning i hear her so one time i went up to her and she said hi "who are you"
and i said i live her whats your name she said lilly,so when i said my name she said that there was something bad going to happen to me.
