Socionics types and flirting

[Kim]

You wana know how INFPs flirt? Quiver away into the nearest corner.... stare at you and not really realize they're probobly creeping you out and then imagine that they actually are flirting with you.

At least this INFP anyways.

Yep yep. I guess it's the avoidant within me, but I tend to completely deny that I like someone if I'm into them. I refuse to go up and talk to them and start up a conversation. Then I go home and let the aching thoughts of "what might have been" consume me.

Ehm...what happens when you fall in love with a friend?
