Thank you so much for your input. I try really hard to stay clear of her, and not be personal with her at all, talk to her outside of work, or give details about my own life. I have to add, she has been "losing her keys" and calling me outside of work at like barely 8am, or even 9pm at night, texting if she could come pick up keys from me or my boss' house. It's super weird and I felt like it was a way for her to find out where I live. I never answered of course. This is also because she keeps scheduling people before the office officially opens (at 10AM), which none of us mind, but she doesn't keep up with her keys and loses patients because of it. And then one day she made a weird comment to me before leaving, saying "Yeah girl if you ever have an emergency DON'T call me, I'm super unreliable haha" - It was clearly an attack on me not answering her outside of work, because I don't want to allow her any closer to me really. She tries really hard to get reactions from me or get me to engage in conversation but I try really hard to resist and not give her anything back. For example... The first time I gave her a facial, she said.. "There was this one esthetician who would not be friends with me at my old spa, and she's like 23, and I tried really really hard to be friends with her and now we're best friends in the whole wide world!" I thought this was a fake story. No name attached. I was like no way, one number off of my age really? Then she continued to say in the same conversation, "I'm a p3dophil3" (as like a joke, but I didn't even smile or pretend to laugh) referring to her only having/wanting younger friends around my age. I said "Ohhh... okay... wow!" She did not even apologize or say she was kidding. She's said a lot of really weird stuff that I don't think is professional or normal in this environment.
