My INTJ sister has never flirted in her life :kitteh: you would have to engage her with deep meaningful conversation to even catch her interest. That being said I really have no idea I was raised in a household comprising of 100% INTJ females and I have never once seen any of them flirt. :mellow:I have a hard enough time differentiating between amicability and actual interest as it is.
Please, I play with my hair when someone is explaining concepts to me. I also do it when I'm bored, as in the apartment viewing with this old ass dude in an extremely shady apartment building. Good thing neither my friends nor that dude have whipped out condoms yet. In the former case I smile because sometimes something amusing comes up and latter to show I'm listening (I'm not).Women also seem to touch their hair when flirting. If she's twirling a lock of hair around a finger and smiling, buy the condoms, dude, you're there.
