one time acquaintance

so last night danielle and I went to this this at OSU, and it was like this international food festival thing called "Taste of Osu". It was very good. I got indian food, french food, and russian food, and even saw one of my russian tutors at it. There was alot of dancing, and just an incredible amount of people there. Danielle and I met up with some of her friends, and we were all talking, when suddenly from across the room I recognize this girl. The girl and I met eachother when I visited Hannah at capital, as did she. I couldn't possibly forget her, because her hair was one big clump of incredibly fine, tight curls, and especially because when she would laugh, it was so high pitched that it would send shivers down my spine. As I was gazing upon her, she looked over at me and made eye contact. Excited, I waved at her. She gave me an extremely confused look. So in return, I pointed to myself, then at her, while mouthing the words "WE KNOW EACHOTHER". In hidsight I realized it probably looked like I was saying we should get together, especially if she did not know how to read lips. So she shook her head no very fast and then turned away and talked to her friends, who were now looking over at me. Great, just what I need, a bunch of college girls I don't know nor care about to think I'm so weird perv. So I call Hannah, in hopes to tell her to call the girl and explain the situation, but alas, she was not picking up the phone. Hours later, once I got home, I messaged her on facebook explaining how we know eachother. I have yet to hear back from her.
