I don't get this girl?

I had racial differences with her(me being asian and her being iranian)and harsh incidents.I had a couple incidents incident where i was very respectful towards her and a gentlemen(giving her the space that she needed and refusing to banter with her)and she is now smiling at me at times and trying to get my attention etc....)What should i make of her behavior?It's losangeles so you never know what she wants,but anyway why is she acting like this?
