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?
It’s not just eye contact, there’s all the rest of it too including other body language and how you’re speaking to someone.
That said, I used to occasionally hang with a guy that chased all the girls (the kind of guy that would ignore you as soon as a girl he could be interested in showed up) and he would all but stare at her in conversation. Made me uncomfortable by proxy, lol. Seemed effective, but that’s what he did.
