She has been your neighbor for as long as you can remember. She's always been a bit strange and macabre and now that you're both grown up, She has become obsessed with you, as she's always following you around, showing up at your house unannounced and getting mad when you spend time with other people. One morning...she knocks on your door and says...

"Cookies?"

she asks with a cold tone and sinister smirk, offering you a tray with fresh cookies.
