lets imagine a nerd guy who hasn't kissed any girl for a longgg
time! and his self-confidence about himself is so low that only success on a few dates will help him get out from this loop(of "im suck! girls hate me!")
Or it could make it worse. A few awkward dates might just make him hate himself more because he just sits there scared or tries to follow some tricks that stopped working 30 years ago. It's foolish.
But some people find it hard for them to even communicate with their gender and need a special technique.
Correct. And these people need to learn to communicate with PEOPLE not just the opposite gender. As for your friend - couples have issues. And those issues are not usually solved by pick-up artists, but rather by couple's counselors. It's not about the gender thing, but rather about communication within a relationship. Which they appeared to have lost.
We can surely disagree, and I still love you, but your views on courtship and relationships are long past their expiration date. :P
correct but you can not ignore from the differences 100%...
communicate with a guy it's not like communicate with a girl.. (It is clear that every woman is a full world.)
And every man is a full world! Aren't you? You're not half a world! :P
There are differences between people. Trying to categorize and generalize might seem like a good solution because it's easier on the brain, but it really isn't. There's no recipe for a good relationship or a good date, because ingredients are always different.
