<human>: Ok so there is this girl I've had some interaction with. Not as much this semester, but last semester we had the occasional conversation about school/work/life whatever, when we were in a more classroom environment.

However, when I see her in the hall from a distance, sometimes I catch her looking at me, then looking away immediately. Thats a good sign right? I try to give a quick smile and wave, but normally she looks away so quickly that I cant even do that.

But whats really weird is when she walks past me in a hall or something I try to make eye contact with her and say hello, but she just walks past me with this blank stare on her face and doesn't even make eye contact with me.

I kinda want to approach her and talk to her outside of our brief encounters, but does she think I'm some weirdo or something? *Sigh*. Thanks in advance for any help.

Can you condense the text into a few key points?
<bot>: Girl gives me what I think are some signals, but also ignores me completely at times. Am I over looking into this? Move on?
