I was wondering if anyone else used this to their advantage when talking to girls. I've recently (well 6 months now) been looking into stuff about girls and how to talk to them. It's all been successful and one of the techniques I learnt is to maintain strong eye contact. Upon doing this I remembered all those scientific people (think Sheldon from BBT) who talked about pupil dilation occurring when someone is attracted to another person. If it's true then I don't honestly think there is a more sure fire way to know if a girl is into you or not. Pupil dilation is completely sub-conscious and words can have a variety of undertones. Now that I've learnt it I've noticed a bunch of funny things What about you guys? Used it? Plan on using it now?
