it was early in the morning, you just woke up, and decided to go check the mail, as you'd usually do in the mornings.
today you had gotten the usual, a few letters and ads. But then you look at your mailbox again and see a package. Which was odd, since you didn't remember ordering anything, but figured it was probably some gift since the holidays were coming up.
you walk back inside and set the box down in your room. After unpacking it, you find a doll, or a plushy to be exact, it looked like a sans plushie, but home made, with a few small rips and a button for one eye. And it was just the right size to fit in your arms comfortably.
you put the doll on your window sill, thinking you'll probably try fixing it up later, and leave to the kitchen to go make breakfast. but little did you know, the doll was in fact alive. And you just left it unattended.
