Have you met any total weirdos?

So, I recently changed cubicles in my office because the company reorganized things. I'm now sitting next to this lady who really creeps me out. She's also an awful human being.

IDK. Whenever people say "Good Morning! How are you?", she purposely ignores them and walks away. She won't even make eye contact. (Well, half the time I can't tell because she wears sunglasses and a bucket hat indoors! How she gets away with this, I don't know!)

There was one time someone looked at her when they said "Good morning!" and she just stared at them blankly before walking around them to grab a napkin. No "good morning to you" or "excuse me". What a b****!!! She basically acts like you have to have "permission" to talk to her

She also has a relationship with one of the cleaning ladies here -- or so I'm led to believe. (They're both about 30.) Today they were putting grapes in each other's mouth in a sexual way, then giggling about it. wtf. They were also saying weird things that I will not elaborate on

I have not introduced myself to her. She scares me.
