As a high functioning, truly, highly intelligent sociopath (well aren't we all) I.... "enjoyed" your book.
I figured out years ago I was a sociopath. I have a brother who is so the definition of "narcissistic personality disorder" his picture should be next to the definition in all books. I personally always classified him as a "psychopath" as opposed to my "sociopath".
Our early lives we moved every few years. Dad was in the military. My brother and I came from an abusive household. I the black sheep, and he the "good" brother. I was physically, mentally and emotionally abused. Mom as well. Little brother got his fair share of the latter two as I recall. Dad never broke any bones. Never left bruises where people could see them. His intention, His terror, was part of his Standard Operating Procedure (SOP) for us. I could see the overall methodicalness of it even as a young child. Keeping us off balance with random acts of kindness and random (or expected acts) of terror. Molding us into what he wanted us to be at the time. Clarity comes with hindsight, I know now that in many ways I had a good teacher. He was a highly intelligent, highly functional man who worked a Top Secret job for the government. He's gone now, not that he'd have spoken to me about it, but with what I now know, I'm certain he was in that APD spectrum somewhere.
Dad not only taught me the "ways and means" of dealing with the sociopathic tendencies, but the "ways of terror" as well. Mental, emotional, physical, all fair game in our household growing up. I always found the physical violence far to easy (I'm a big guy and can physically dominate most people easily enough) and prefer the mental and emotional manipulations more; more of a challenge. More "fun". Anyone can physically MAKE someone do something (say with a gun if nothing else), but manipulating them into WANTING to do it, far, far more satisfying.
I have really never had much of a chance to actually discuss the intimate details of our "disorder" with another sociopath. All us "APD" people have similarities. A few of the similar SMALL details however, of our (yours and my and perhaps others)"condition", "blew" me away.
The fake accent. Mine is a non-specific southern accent, "blunted" by many years of living in the Midwest; or so it sounds. Seems to instantly set people at ease. "He's just a good ol' boy." Hearing the consonants roll off your tongue. Funny enough, I used to do the "non-specific European" accent and dropped it for the "non-specific southern" accent, as it was proving to be far more useful and continues to be. I wonder if this is due to our "chameleon" abilities or is there some other underlying mental process that makes us change our speech?
The "sharp tooth". Wow. Such a small detail, but on the mark. Likely due to our "sensation seeking". Had anyone bothered to ask, I could have told them 20+ years ago I was a dopamine junkie. I truly believe we do not produce enough dopamine, which causes us to live our lives constantly searching for some sort of stimulation, so for a brief moment we can have "peace". "Feel"......"Normal"?
There were a few other small details as well that I did not expect. Playing drums and living in bad neighborhoods being two of them. Makes me wonder how much of the "us" we have is really us, not just a response to our expressed genetic heritage. I'd be curious at how many others you've communicated with have similar "accents", "sharp teeth", are good at keeping a beat and live in bad neighborhoods.
I have delved into BDSM for quite a while now. Yes, surprise-surprise, I'm a Dom. Choking, pain, asphyxiation; all can certainly be "fun". Knives are "fun" as well.
The sexual "deviancy" and attraction to the BDSM world is more common among APD people I've noticed. As well as MANY other mental disorders it seems. A fertile playground. Not without its downside. I've had two stalkers in the last 10 years who didn't take kindly to me just dropping them from my life. Of course what really happened was I decided it was over, and manipulated them into either leaving or stepping over the "line" and doing things there was no coming back from. That cost/benefit analysis can be a bitch sometimes. Mostly for others.
In this day and age of sarcasm and violence, I often just speak the truth now. Just like the person you quoted in your book. People think I'm joking. At worst, I have a slightly "off" or "dark" brand of humor. "What are you thinking?", she asks. "I'm wondering what kind of noises you'd make if I held you down and bit a chunk out of your shapely ass." She laughs. I was telling the truth.
I'm really not sure why I'm writing this email. Certainly curiosity. I have never shared this information with anyone.
In some way perhaps its comforting to know I'm not alone in my "uniqueness".
