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?
Yeah people like it when you take a genuine interest in them so asking about their hobbies and passions is also a good way to flirt. Basically you are trying to give the other person the sense that you are equal parts interested and impressed by them.
Edit: Been with my wife for 13 years now so this is probably bad advice for youngsters. These days they likely stare at their phones and send aubergine emojis to each other while sitting 2 feet away
I’m not yet 30 and I think it’s good applicable advice. I think you can actually practice a lot of these skills by making friends. The difference between romantic and platonic isn’t that big.
