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?
Well, I got the impression that the author was mostly hanging out in upper class society. So while she’s asserting that these rules are universally applicable, her frame of reference seemed to be mostly talking to people in situations like fundraisers and galas. I imagine she’s operating on a framework of always having some prior knowledge of the people she’s engaging with.
