The Ghost in the House

One night when I was about 17 I spent the night with a friend from school. We were in her room when I had to use the bathroom. As I walked down the hall I glanced into a storage room where I saw a young girl just standing among the boxes. I waved to her and she waved back. I didn’t think anything of it and used the bathroom and went my to my friends room.I asked her what her little sister’s name was figuring she forgot to tell me she she had one. After all, we’d only been friends for a short while. She told me she didn’t have a little sister. I asked her who was in the other room playing. She accused me of trying to scare her and when we went back to the room there was no one there.While we were looking for the girl, I made my friend search the room to make sure they weren’t playing a trick on me, I happened to glance out the window and there was the little girl, under the security light. I called my friend over, but when she got there the girl had vanished. Mary thought I was a little weird after that, but I KNOW what I saw. we stopped being friends and I wasn’t invited back to her house. But I saw her, I swear!
