I think she now likes the fact that your harder to get and your a bit of a challenge especially as your out and about majority of the time and she wants to grab your attention. From here it seems like she's slowly falling for you. Keep doing what you usually do though don't change attitudes towards her as that's what's making it work I guess :S Don't play too hard to get though that could make her think "I'd never get him" and just give up eventually.
And well.. if you didn't know X = kiss O = hugg. So.. Kiss Hug Kiss Hug Me personally, I used to use it casually if I liked a person or even to a tight friend of mine But from 'k' to 'xoxo' .. you must be doing something right (.
Before she just liked you as a friend... now maybe shes starting to consider you a good friend and shes starting to like you more. So shes more comfortable wit u.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
