You can read most people like a book, but today figuring out the new person on the scene is not going to be as easy for you as it usually is. They are friendly and outgoing enough, but the signals they are putting out in the world are decidedly mixed. Instead of working yourself into a lather trying to pin them down, step back and give them space. Show them that you yourself have some mystery to offer. Turn the tables fast enough, and soon enough they'll probably be pursuing you!
