There was a girl slightly in front of me and to the left, she had her hands in her back pocket with palms facing outwards and she kept glancing at me and looking to see if I was looking at her and then looking away. I just acted like I didn't notice her because didn't want to give off any wrong signals. Was she nervous or?

If she was indeed looking at you, to see if you were looking at her or not, it was a sign on interest.

In a way, she was enticing you to hold eye contact with her. She was displaying her interest to you, without being verbal about it. An "IOI", if you will understand it that way.

Your remaining neutral to the whole interaction gave her the "Not Interested" message.

Next time, be a bit more confident. Eye-contact is one of the most powerful tools of the attraction process. A lack of eye-contact suggests low confidence. Not a very attractive thing, to women and otherwise.

Well it seems I am always catching her glance, the one time walking down the hall and it was only us, I was walking one way, and she walking another, as i came closer she looked into a room that was closed, like noone was in it and it was dark, and soon as I passed she looked back straight.

Vatalli if i was you the next time i see her i'll walk up front with a smile and a hand shake say hi and my name, as she reaches for it i say" one two three four i declare a thumb war".

it doesn't matter if you win or lose, but this shows you are confident, funny and its a fun game

take it from there show her your interesting i believe in you
