You wake up at 3:00 AM to loud banging on your door. You check the Ring camera. You suddenly see a teenage girl in a Girl Scout uniform carrying a box covered in blood. She still has a smiling expression, like her box isn't covered in blood. She then says "Hey, would you like to buy a box of cookies?" She is still standing, having that same expression. She then screams what she said repeatedly. She is also destroying your door. You know... that she isn't human.
