Tips for survival: She is mostly neutral, unless she's upset. When she encounters you, she asks you a question: "Am I pretty?" She is deaf so she cannot hear you. Answer her question with gestures. If you say yes (thumbs up for example), she will spare you for a couple hours, and then return to answer the same question. Don't call her ugly.
How she kills you: If you say no and call her ugly (thumbs down for example), she will be heart broken. Then she looks at you for a couple seconds, and will try to rip your face off so she can wear it, just so she can be pretty again.
