How interested is she? We're both in college...brief library encounter?

So I meet a new girl in the library elevator and say a quick hi and move on. We're both in college. I'm laying on a couch and the same girl walks by later and I call out to her. Then she walks up to the couch im laying on to say hi. I told her I forgot her name and then I'm like "so do you remember my name?"





And shes like "no." So I say, "oh, well thats too bad. I guess now you'll never know!"





And shes like "but i have to know!!" And then from that point on I just tease her for a minute. And she kind of giggled the way through the convo.





But she really was in a hurry so she walks away to study. I pop open my laptop 15 minutes later and she's already sent my a facebook friend request.





Anyways, girls, how interested is she? Keep in mind, she is a REALLY REALLY outgoing girl so thats why im confused.
