<human>: I go to a separate school on saturdays for extra study and preparation for exams. In this school the teacher doesn't know our names and we don't know each others. Almost like a lecture. 

3 weeks before christmas, I noticed that this girl keeps looking over at me. She seriously will not stop. It makes me feel uneasy, paranoid and self-conscious. I think about how I look, what I wear and how I sit. I believe I have social anxiety although this is just what I think. I find it very hard to meet new people and I'm very shy, although I am quite loud with the people I am close to.

Anyway, she keeps looking over at me each week, sometimes periodically and sometimes as looking at the board I can see in my peripheral vision that she is facing my direction. I do not think I am paranoid and making it up, in fact a week ago I had to courage/was frustrated enough to actually turn and look at her, and looked straight in her eyes even making her embarrassed. I feel she is looking for attention. After all of this, i found myself somewhat interested in her, she almost seems to play with her hair to get my attention on purpose. I have tried to talk to her on 2 days, but always have been stopped by the fact that she was talking to her friend or by the fact that there are too many people walking in the corridors. Really I think I am making excuses to myself

I've planned on making a remark about her turning around in class when i talk to her (and definitely thought too long about how I'll phrase it).

How can I get the courage to talk to her and stop making excuses to myself? Is it really best to talk to her or maybe I should ignore this?

Mostly I feel bad for her wasting her time. She pays to come to class and does not focus and causes me to also lose concentration

I should also mention that next saturday is valentine's day, if this is relevant at all.

All comments appreciated

<bot>: There's a girl in my class that stares me out. I barely have the courage to look at her in the eyes. How do I approach her and what should I say... if anything?
