She has a shy personality. When we talk in a group settings, she is pretty normal. When she talks with others, she is pretty normal too. However, conversations with just me seem a little awkward. She fidgets in her chair, messes with her clothing accesories (watch, zippers, necklace), blinks quickly - lots things shy girls do. Conversations are bad though, it's generally the two of us laughing and smiling the whole time; I feel that she has a different personality when we talk.
It's a little obvious that I'm interested in her. I've asked her out a few times and we've have met up before. The last two times, she has been busy. On the last occasion, I asked if she wanted to go to a festival/fair together that weekend and she immediatley said "yes" but thought it was the next weekend and a few seconds later told me was unable to go because she was busy. Her words were "let me know when the next one is!" - which to me, sounds like she just wants to be friends.
