<human>: It's not really that important, but here is my situation: I [20 M] just formally met a girl [19 F] who I have kind of admired my whole life (we went to the same school our whole lives).  I would say we have very similar tastes, we watch the same TV shows and listen to similar music etc.. We get along well and sit together in class.  I am attracted to her and in my opinion she would make a great girlfriend.  However, she has a boyfriend at the moment so I can't make any moves right now.

How do I know if I have made a new friend or met a potential girlfriend? What is the difference? The only friend I have who is a girl is my sister so I don't really know.

Can you provide a brief overview of the text?
