Shy girl's body language?

Anonymous
I have heard that they aren't obvious with their attraction signs and are more subtle. What about pupil dilation.

There is this one girl I like who is extremely shy, and mostly avoids me, until I approach her one on one, then we talk and she always has a question and an opinion.

I just recently noticed that when we talk her pupils become massive, I can barely see the blue in her eyes, and she smiles a lot. She also gets fidgety, once she accidentally cut herself while talking to me, or she will accidentally drop the toys she is stocking. She works as a sales floor associate at a Wal-Mart so she has to look busy. Since I work in the same store with her, I am obviously not a customer.

Judging from this I am unsure if she likes me though. She is usually super quiet around people. Also with me when others are around, like I mentioned before alone it is another story. However it must be me who starts conversations, otherwise she avoids me. Don't know what to think. Does she like me?

I should also add that she talks a lot during conversations and has also taken an interest in me learning about her culture, she is Slavik. Whenever I am around her she brightens up. I have not seen this but my friends have.
