Everytime we see each other in the hallway at school we'd always smile at each other but that's it. I talk to her sometimes in class and on fb. Thing is I'm not really sure if she has a bf and today I feel her replies aren't as "warm" as they were before o.O but maybe that's just me freaking out. Oh yeah and I'm not sure how to tell if she's just smiling politely or if it's because of something else ...
