Recently I have been practicing making eye contact with men and women in general. But I cannot figure out if the eye contact shows interest or not. I read somewhere that if they look downwards with a sweeping motion, then it is a sign of interest, however if they look and their eye reverts back ahead it shows no interest. I have been getting stares for 3-4 secs but they generally revert the eyes straight ahead. Does this mean that they lack interest? Would love to get your views on this.
