LoL mate you should have asked her ... why not?
If this girl just reply that she is not interested, you could tell her never mind sorry you were looking like some one I would like to meet !!
I hope you did not mean this?
No meter what a reply you get you always can try to change her mind about ya...
anyways if the girl is just to havy and acts like you are to low for her just give her a look that she is strange and pick up anther girl in the same place.
