I won't lie, I wish I had that talent...
Though for me personally that does create questions of how to balance the fact that I genuinely care with things like time limits and the fact that other people typically care about my welfare vastly less than I care about theirs. The fact that I tend to genuinely care about other people has gotten me taken advantage of at times. I am more careful these days about trying to vet people and make sure they aren't all "Yay! Freebies! This dumb bitch is just giving it away and I am going to take all I can, as long as I can, then disappear if she expects something in return."
People who are already socially confident don't think about these processes because they just happen naturally for them. You meet someone, chat with them, and then sometimes you become friends. So when someone comes along and outlines the process, it seems clinical and detached, and thus kinda creepy.
Certainly it was my reaction when I first started seeing things like this. "If you're thinking about it, you don't really care about the people. Real relationships just happen naturally!"
But of course, for some people they don't just happen, and these kinds of outlines can be very helpful.
But it takes 15 to 20 hours a week to establish and maintain a genuinely close relationship. Forty five minutes is barely a down payment on that.
I have known "players" and how they operate. They are good at creating an illusion of closeness, often based on outright lies. Their goal is sex, and her welfare be damned.
Forty five minutes is also not enough time to verify if what they are telling you is something genuine. It can take weeks to learn that what he shared day one to make you feel all squishy is all made up BS.
So 45 minutes may be enough to create certain feelings, but if you think that is genuinely a close friend that you can trust, you have a lot to learn about how relationships work.
It's a big flipping deal to a lot of people; don't presume everyone is you.
I think all of that is uncalled for, overly personal and essentially an ad hominem.
It takes more than a one time 45 minute conversation to create and maintain a close relationship. There is lots of research about that.
