Just curious. Winking is perhaps one the most effortless things you can do to send another human mind into a compete state of confusion and intrigue. Is winking at a girl ever acceptable (if she is giving you iois of course) and if so in what situations? Or is it just creepy? I was mainly wondering because I was walking to class today and saw a girl eyeballing me (we were walking opposite ways) and as our paths crossed and she looked up from her phone and gave me one last smile I really thought about winning at her just for the thrill of seeing her reaction.
