what is this?!

There is one classmate, for one semester I don't talk to her, because of one character of her is very obvious and I felt annoyed of it. Suddenly, she added me in Facebook and commented on the status that is so damn common and that Facebook status, that time, my best friend commented on it, she was like just came in and said "jia u jia u". Well, for her as a Facebook user, I appreciated that, but not from people like that. I am not "complaining", but just, is hard to accept that. I am sure she actually knows that I felt annoyed of her. She is kinda benefit-minded person. Is too obvious...=.=

And one thing, which I feel very awkward of it. She even smiled at me when we meet. I replied the smile, and I HATE the smile that I gave. I think I better keep my cool face. Seriously, the situation is like forcing me to smile. Actually I don't wish to smile at all. For one semester I don't either talk or smile to her, I "don't know" what to respond for this.

Shall I give her a chance and to myself to "accept" her as a friend? I discussed this with another friend who is also coursemate. My friend said since is going to be last semester for Degree, so just bear with it, try to accept. I have been thinking of my friend's pieces of words. Is it because she knows that I am a person who value friendship, so she takes this to "tackle"? Come on, maybe she doesn't know that, I won't entertain any kind of people that easily. And I am not a fake person. I can be a person that can talk to easily and nicely but depends who is the person. Somehow, after certain incident, I couldn't put more trust to any people, if I am willing to put more trust, means the person is really trustworthy (this is more comprehensive if I put this sentence in this way). This kind of person actually made me lost trust to people. I won't want to get myself hurt again by this kind of people.

So? Accept or ignore the nice act and manners from her?
