Is this girl gonna get mad or upset at me?

In my college cl, there is this hot girl that I feel confident likes me. When she sat next to me the other day, she kept shaking her foot, almost causing her sandals to fall off, she did some preening when she was around me too (ie fixing her shirt, putting on lip gloss, fiddling with her hair). At the end of the cl, the teacher had us read an article and she didnt print it out, and wanted to look on with me. Unfortunately, this other hot girl already asked me earlier in the cl (before the girl I like came in) to look onto my printout and moved her desk toward mine. I couldnt help her out and she had to look on with somebody else. My concern is that next time I see her, she will feel mad or upset that I couldnt help her out, since I know that girls sometimes get emotional over stupid little things. Should I be concerned, or will she forget about this episode after a few days?
