I came across this older podcast from This American Life entitled "Allure of the Mean Friend".
I especially liked the first section. In this a middle-aged radio reporter interviews a good friend, who had been a mean girl that tormented him twenty years before in middle school.
And it's really something when he sends his nerd friends out to interview her older sister, who was even meaner. Those middle-aged men report back that she's still intimidating in middle age.
I found this all fascinating. I was friends with a lot of mean girls in school (but not mean boys). I must've got the message though, because I didn't pursue them for relationships when we got older.
FWIW: I can't be sure how I'd act in person, but I found the voices of the two sisters interviewed in the first section to be alluring over the radio. I wonder if there's something in their voices, rather than their meanness?
