so what do you think (girls opinion please)?

okay, so this may not be too much of a question but i just want your opinion on if you think she is into me or not. ill try to make it easy to read

-every time we run into each other or talk before class she makes eye contact and smiles.

-we've had a couple of classes together but this is the first we've had where we actually sit next to each other and we talk during class alot. her sorority sister is also in the class, and when i introduced myself to her sorority sister and told her my name she replied "oh i know, i know ALL about you" (obviously caught me off guard) does that mean that she has been telling her about me, because i have never met her sorority sister before in my life lol

-we comment to on each others facebook status's alot

i know its not much to go on but i was just wondering what you think, plus its an easy 2 pts.

and i was thinking about sending her flowers on valentines day, do you think that would be too much considering we havnt actually been on a date?
