I have heard from multiple people that eye contact is essential in letting a girl (or guy, I guess) know you’re interested.
But what is the 411 when it comes to said eye contact? Do you keep looking until she does? Do you then keep staring? Or is like looking at the sun? What’s the deal?
The trick is to never look away. Stare till they notice, then keep staring. Have to get up to use the restroom? Maintain eye contact as long as possible and reestablish it the moment you’re back in sight. If they get up, the responsibility to maintain that eye contact is on you. Make sure to stay within eyesight, following them if necessary. This is your chance, we’re rooting for you!
