The Doll

I won the doll for my overly demanding daughter at the fair. Big, creepy doll with eyes that close when you lay her down. Things got weird that night after we got home. Walking past Lydia's room, I heard talking. I heard two distinct voices but when I opened the door only her and the doll were there.
"Was that the doll talking?"
"Don't be a ninny. Of course it was."
The Doll has become a welcomed addition to the family. She's polite, she helps Lydia with her homework and helps around the house. She's the daughter we always wanted.
