I've been talking to a girl on facebook and I just recently found out we are in the same class (hey its a realllyyy big class, ok, so I didn't know). Anyways, we've been mostly talking about school-related things such as how much this class sucks or how we did on certain test et cetera and she gave rather detailed responses, in other words she wasn't half arsing around like someone who doesn't want to talk to you usually doess. When I found out she was in my class, I basically said something along the lines of "Btw, I feel rude....we're in the same class and we haven't even spoken yet! just doesn't feel right. I'll fix that

". The thing is I sent that 2 days ago and she's been on facebook since but hasn't responded. I don't plan on messaging her again, because that seems clingy to me, like I'm pressing too hard for her attention, I'm just waiting for her to respond. What's the deal? Was I too forward (which I doubt cause) or is she waiting for something?
