A part of life?

I met somone last night out the blue...and i mean completely random. Earlier in the day i talked to an old long time friend and he was mentioning about how he was looking for a chat room where he can talk to people about his problems and seek advice...and this was before i even told him about blogtv. I know i should go back on but i'm scared. Anyway can someone tell me what does it mean when you meet someone with almost everything in commun and can sit there and talk for hours and not get bored of it? Someone said it was scary cause she was like the female version of me. I don't know...the majority of me is really saying move along...but there is that little thing inside of me saying it doesn't care if he gets hurt if he does try and pursue something with her but finds out she isn't interested. But i can safley say one thing...she would have been or could have been something I would have been proud to be with. She is very passionate about her work and teaching. There is so much i can go on about her, but no point for now as she can and could be just another face i meet in life. I hope it's not the case.
