I always give 'me and my coworker' as an example.
One of my coworker is one of the most socially inept/introvert person I ever met , she even has some kind of people phobia, like she cries sometimes when she's in a crowded place or if she's somewhere with too many strangers. She sometimes sound too unfriendly and too distant.
Her self-esteem and confidence are less than zero.
She's undereducated (not idiot tho) compared to others here : zero in English , 1 over 10 in French I would say and computer challenged. She's an extremely village girl (was once extremist muslim) , she was very closed minded and the city life was so alien to her.
She doesn't drive , doesn't club, doesn't swim , doesn't do any outdoor activities.
Yet , despite all that , she had tons of bfs (most of them from the city) - just because she's a bit pretty . Her last bf is a Christian strongly-agnostic from the capital city and she got him just after FEW months of her break up with her ex , and there were other guys who wanted her too.
I have a lot in common with this girl (when it comes to lifestyle or personality traits, not mentality) but ,unlike her I had no partner in life (gfs, I mean). When a female human is less than a social beta = not a big deal = doesn't affect mating chances much , but that's not the case with the males.
Forget about me, just imagine a reverse scenario, a guy with the exact same traits of that girl , how many gfs from the city he will get?
