It's obvious that you ignore her.
And whether or not you care to admit it, it APPEARS, to say the least, that you're rather passive-aggressive towards her.
Now, I've gotten to know her very well, and I can certainly say that any negative characterization you have of her is probably undue. Please consider that whatever you think you know of her, you only know her in a superficial manner through PMM and perhaps some online exchanges. She deserves a little more benefit of the doubt, and you only make yourself out to be ugly when you direct your cold shoulder and passive-aggressiveness at her.
I'm not suggesting that you become her friend. But whatever you have against her, let it go. It's not worth your time or hers.
