...not sociopath either. Not what I'm seeking. Not that extreme.

Hi again,

Frankly, I am rather glad that traits less severe than sociopath haven't yet found their way into the doctor's textbook. Introverts risk to be perceived as less empathizing than extroverts. My capacity to empathize may also depend on my mood and on other fleeting circumstances..
BTW, the German language doesn't offer a wider choice of terms in this field. The recent emphasis on empathy most certainly originated in the Anglo-saxon culture (Rogers and followers).
