if you can be manipulated in any way by other people's emotions, like even the slightest, you probably aren't be a sociopath. you just probably have bad social skills and need to develop your sixth sense.
I'm talking about TOTAL lack of empathy, subconscious recognition of body language. sociopaths don't recognize body language nearly as well as other people. again, also just might be bad social skills.
sorry for the dub post, I have been hospitalized for this shit, I'm a clinically diagnosed sociopath/psychopath...they revoked the label after I went sober and showed them I'm actually a pretty damn happy and nice person when I want to be. I just went fuckin nuts for a bit lol.
