Indeed, the power of eye contact cannot be underestimated. This mode of flirting is otherwise also called as an eye smile. The eye smile involves giving a provocative look to the intended person. However, it is much more than just a routine smile since the eye smile also lays stress on the fact that you communicate your intentions nonverbally. This method is very much apt and helps convey your feelings in a manner that even a thousand introductory phrases fail to do. Hence, it is a very safe bet. Yet, prior to trying this technique, it is better if you engage in a practice session first because an overintense gaze can do more damage than a stupid conversation starter.
