<human>: Took a summer class with this girl(23f) and she seemed interesting. I(23m) started to ask about her and what not and responses were good. She had follow up questions as well. She would laugh at my jokes (even though they were whatever) and even mimicked my jokes back at me. I did offer to help her study but she never actually took it until near the final. When I finished the final (about an hour earlier than her) I waited for her and when she came out, I asked her how she did. She was like "you're still here? and ehhhh" (about the final) and walked off. Btw another friend came out at the same time as her and started talking to me when I asked her that question. Honestly my first impression of that response was wtf.... so I had to cut my friend short and started catching up to her. Called her out a few times but no reaction until I got closer and asked her why she was heading off so quickly like that. She responded "I wasn't walking that fast". (looked fast to me >>)
We talked as I walked her to her car and everything seemed normal so I asked her if she wanted to hang out and her response was very vague. She basically said her weekends are kind of busy and during the weekdays she seemed open but she didn't specify when she'll be open and that she'll let me know. (I did notice a higher pitch in her voice when I asked her if she wanted to hang. Her response was "yea" with a higher pitch voice). I did read that people do that when they lie. Also that if I were ever to drive near her area, I should let her know to hang out (not sure if this was a sign to do it or not). So is this a waste of time or should I pursue and ask again for a more specific date.

Could you distill the essence of the text into 1-3 sentences?
<bot>: asked a girl to hang out, response was very vague and open ended. Should I bother to ask again or move on.
