Well, I've never had any relationships since birth, but I can easily talk to the opposite gender. The thing is I don't know if that person "like like" me and I don't notice any different behaviors in any of them, they are all nice, approachable and shows no sign of shyness, so I assume they are all only in friendly terms with me. So, my question is how would you know if someone "like like" you?
