The strange birthday party

It all happened in a sunny day....yes.....like in all horror stories.....it all happened at Teressa's birthday party.
It was a hot day....so hot like a fire.
Me and Teressa went to shopping and buy-ed some cool clothes for the party We were so happy because she is finally 15,and because we wanted to make the cool party ever.
When the kids arrived at the party me and Teressa had the greatest outfits .It was the coolest party ever.
When the guests went home me and Teressa were prepared to go to sleep(I was sleeping there)when someone knocked at the door.
It was just a poor young girl She asked if we have something to eat The same story happened the next 2 days.
Than Teressa's mom and we went to police and she told the police man the story with the girl........but......after she said she saw a picture with a girl......and than she said:"That's the girl" ,but the police man told her that it can't be possible because that girl is.............dead....and she was.....because the police man explained to us that a 15 years girl died in 17 September in that house........and Teressa was 15 in.......17 September.
