Rather than looking at others "from the outside", empathy is trying to see the world from their point of view.
It is also conveying the desire to know another person, understand them, and learn from them.
Too much rapport only and a strong friendship will develop without passion (what the PUAs might call "let's just be friends").
It helps you to truly create Rapport with the ones you love (or want to).
So, it is quite possible to do so, while also maintaining those three pieces of rapport.
It just takes leading (with rapport) towards your desired goal for the interaction.
Also, if there is something specific you'd like discussed, either comment or send me an email about it.
I do take requests and get to them as I am able :) Actually, I've been thinking about this issue for the last couple of days, and my take on this right now is that, while "making friends" seems to involve basically making a lot of rapport, seduction and persuasion seem to require a good balance of making and breaking rapport. I guess that's where the mind games and seduction methods try to bring a roadmap...
It requires that you are aware of your own feelings and present them to others, rather than putting on a "fake" attitude that is separate from what you are really feeling.
