There's a co worker that seemed nice enough when we started together, but as time has gone on she's become really awkward to be around. She always has a tense presence and she acts apathetic and indifferent when you say anything to her. So I don't talk to her. Later she complains about me, talks bad about me, or makes hints about how weird I am to other people. I don't care I guess - but if she has a problem with me, why doesnt she leave me alone like I do with her. She even complained to management that I make her uncomfortable (even though I don't speak to her) and she continues to hang around my area or she'll walk by when she has the chance. It's annoying and I just keep to myself - but for curiousity's sake I do wonder why does she act like this??
