This is a story I found while browsing /r/ForeverAlone, although it's originally from a website called Slate Star Codex. If you're confused about why "personality" is mocked so mercilessly here, you need to read this:

I had a patient, let’s call him ‘Henry’ for reasons that are to become clear, who came to hospital after being picked up for police for beating up his fifth wife.

So I asked the obvious question: “What happened to your first four wives?”

“Oh,” said the patient, “Domestic violence issues. Two of them left me. One of them I got put in jail, and she’d moved on once I got out. One I just grew tired of.”

“You’ve beaten up all five of your wives?” I asked in disbelief.

“Yeah,” he said, without sounding very apologetic.

“And why, exactly, were you beating your wife this time?” I asked.

“She was yelling at me, because I was cheating on her with one of my exes.”

“With your ex-wife? One of the ones you beat up?”

“Yeah.”

“So you beat up your wife, she left you, you married someone else, and then she came back and had an affair on the side with you?” I asked him.

“Yeah,” said Henry.

I wish, I wish I wish, that Henry was an isolated case. But he’s interesting more for his anomalously high number of victims than for the particular pattern.

When I was younger – and I mean from teeanger hood all the way until about three years ago – I was a nice guy. In fact, I’m still a nice guy at heart, I just happen to mysteriously have picked up girlfriends. And I said the same thing as every other nice guy, which is “I am a nice guy, how come girls don’t like me?”

There seems to be some confusion about this, so let me explain what it means, to everyone, for all time.

It does not mean “I am nice in some important cosmic sense, therefore I am entitled to sex with whomever I want.”

It means: “I am a nicer guy than Henry.”

Or to spell it out very carefully, Henry clearly has no trouble with women. He has been married five times and had multiple extra-marital affairs and pre-marital partners, many of whom were well aware of his past domestic violence convictions and knew exactly what they were getting into. Meanwhile, here I was, twenty-five years old, never been on a date in my life, every time I ask someone out I get laughed at, I’m constantly teased and mocked for being a virgin and a nerd whom no one could ever love, starting to develop a serious neurosis about it.

And here I was, tried my best never to be mean to anyone, gave to charity, pursuing a productive career, worked hard to help all of my friends. I didn’t think I deserved to have the prettiest girl in school prostrate herself at my feet. But I did think I deserved to not be doing worse than Henry.
