Search Results: they laughed when i walked by

We've been been friends for about a year and I have a class with her
Things I've noticed:
-Doesnt smile a lot but Smiles a lot around me
-when We walk, stand, sit, etc. next to each other she's usually close (like legs/shoulders touching close)
-when we work together during class that if our hands touch accidentally for whatever reason she won't pull away.
-When we lock eyes from a distance she always flashes me a big, genuine smile
-i notice her staring at me when I turn around to talk to my friends in class
-She either holds my gaze for a bit to long or she quickly glances down and smiles when our eyes meet
-She gets really giggly sometimes and laughs at almost everything I say
-When she's in a bad mood, she instantly brightens up around me
-When I pass by her friends during the day they seem oddly silent, their whole little trio will be quiet but they see me (at least it seems so)
-Sex jokes/ doesn't mind talking sexual
-little suggestive comments for ex. Once another girl asked me for something she cut in with, "I come first" and the other girl backed off
-in my personal "bubble" a lot
-Doesnt get mad if I get caught 'looking'

Sometimes she won't text back though and she can be a bit forgetful..

by the way I'm not usually this clueless with girls, just this one lol
