- When I look her way (she sits next to me), she avoids eye contact, or looks away, or sort of stretches her neck
- When I've looked her direction across the room, she looked up at me (I didn't catch her stare... I was looking at the person speaking next to her lol)
- When I was walking slowly up the stairs to class, I noticed her behind me; she could have easily passed me, I was walking really slow, but apparently she didn't
- BAD sign? : I walked out of the bathroom, and I look at her walking behind me, but she isn't looking at me ... same thing happened after class...

I don't want to make wild assumptions, which is why I'm posting this.  Are these generally go-ahead signs to try and talk to her?  Or could she just be a timid girl in general?
