that time at the reference library I sat down at a crowded table and a guy at table away looked up as I was sitting down to see who was sitting down, smiled at me and sat up taller as though he knew me from some where else and then when I didn't respond looked troubled frowned and went back to what he was reading.
how this incident could be used in a fiction. a person is at the reference library as he sits down a guy looks up from a few tables away, raises his head completely, sits up back to back of chair knitted his fingers together on the table even gives a little smile. like he knows him from somewhere. he goes back to his book when the person makes no response to his behaviour.
a few weeks later as the person is exiting the elevator at the library a similar incident occurs, this time a young asian female looks up, sits up, knits her fingers together on the table and smiles, almost as though some one behind the person is motioning these actions to her. he walks on and she makes a deadpan face.
some couple of weeks later as the person is walking through the cumberland terrace the guy and the asian girl from the library are standing near a jewelry store. she is bent over in front of the guy like she was giving him a blow job though her head is turned and she is smiling at the other guy. her friend is staring off into space with a grin on his face while a line of saliva drools from his mouth on to the girls head. the person is a little startled by this and exits to the street on his way to the yorkville library.
when he arrives he makes himself comfortable by the magazines. In a few minutes the couple from the hall way enters the library, the male glares at him, motions to the female to sit in a chair with her back to the other person but in line with the chair he is sitting in, and then the guy with the asian turns his back and starts looking at magazines on the shelves. while he does that the asian girl gets up and moves quietly to the shelve opposite the ones her friend is standing at and begins siding along the magazine shelves, slowly closer and closer toward the other person. all the time pretending to be looking at the magazines though taking looks over her shoulder at the guy who had turned his head so he could see what she was doing and encourage her with nodding motions of his head.
So the other person gets up slaps the magazine he is reading on the table and goes to the bathroom. when he gets back they were gone, but not for long.
