If she is mean to you?

I came across this article and it went on to say that when a woman acts mean towards you, It's actually a good sign. I am not so sure about that. There is this woman I work with, There has always been a sarcastic banter there, But lately she has been really digging the boot in. I give her backhanded comments however I am actually starting to think this woman dislikes me severely. As soon as i walk in the room the first thing she says is "oh no not idiot again". I usually comment with something like "sit down and do some work" she is hard to read and have no idea if she is serious or not. I just try and shrug it off with a sarcastic comment. What do you think?
