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?
Consent. Body language is just words with a more physical language, so you’d act similar as you would with words. If the interest answers with positive eye contact it is more likely that the interest is mutual in a different language as well, but NOT a given. Gist: Listen with your eyes.
But how is OP meant to do that if they don’t know what they’d even be listening for? I’m not single these days but I never figured this whole body language thing out either, people’s movements just don’t seem to mean all that much.
