Is she interested or I'm very observant?

Only girls can answer this. If you are a guy reading this, you are mad gay.

Setting is in college.

I'm a lefty and people who go to college know that the left chairs in a row (in lecture) have the desks on the left side. So I'm always stuck sitting on the left side, otherwise its a *** writing on a righty desk when you're taking a scranton test, note taking or anything with writing. But anyways, this girl always sits in my row but on the other side of the row (so on the right side but not on the end, 2-3 sits in from the right but about 6 chairs over from me). Every time I see her she always fixes her hair but she has never really looked at me (She may be but I haven't see her do it). She's either always touching her hair or looking down at her iphone when I look at her.

Well, today, this was kind of odd but I'm not sure if this means anything at all. We had a very short quiz and when she turned in her quiz, she could of just walked down the right aisle but instead, she went across all the seats and wanted to go down the left aisle. Basically, she went down on my side but it would have been such a shorter walk if she went the other way. So she said excuse me and I just moved a little so she could pass. When she returned to her seat, she came back my way instead of using the right aisle. We had a lesson after the short quiz and that was pretty much it. Nothing else and just left. Could she be doing it so she can be noticed or what?

Nobody was sitting in-between me and her and maybe I'm thinking to much or something. She could also be shy but I have no clue.

Now I would sit close to her but like above, I'm a lefty and these little desks suck so bad. You can't run a laptop so its pen and paper only for note taking.

She doesn't sit next to anyone at all, she sits all by herself and doesn't talk to anyone but the people on her iphone.

Now, I'm an extremely observant guy but I do pay very good attention to the professor. I'm just noticing these odd things lately.

Mabye you should start talking to her get closer yes playing with hair and getting your atenshion is a way of show she likes you but she might just try to give you something to talk to her about so you can sit next to her

Well now we all have a very good understanding of the geography of your class room and who sits where! Quite honestly I wouldn't waste my time on someone who does nothing but fuss with her hair and only talks on her iphone. She sounds very shallow. Have you asked yourself why she is not popular with loads of friends? There seems so little evidence that she has even noticed you, let alone wants to talk to you, so I would advise you to cut your losses and look elsewhere for a girlfriend. Sorry.
