Not sure how else to word it, I am not a very good judge of attraction but seen things that look like signs of attraction such as I am looking out of window on bus or train and turn my head and see a girl just stare at me, no anger or shock to their face either friendly looking expression or a blank one and they keep turning head and back to me, sometimes even playing with their hair, or a little nervous not in the worried sense.
But sometimes when I have noticed this I have been given rude comments like "what are you looking at" or "stop looking at me" so its hard to tell if either they are just self concious and thats why they were looking, and/or they assumed that despite me only turning my head as they are looking in my direction constantly I was somehow looking at them, or that they are attracted but dont want to let on they are.
I say that because I remember growing up I had girls who would claim to dislike me but then want my attention because I was nerdy and unpopular, some years later told me they were attracted to me and it was just they were afriad of being cast out for liking me and I assume often somethng still happens now as I have had girls be rude to me then seem to go out of their way to be near me such as in a club(big club, multple bars yet they always seem to go to one I am at and stand near where I am)
