Since learning this stuff something interesting's happened: long time female friends have started coming on to me (for the record, I haven't been running game on them, just being my new self). This is what one would call a quality problem.
Some examples:
While playing a drinking game...
Me: Jeez, I'm getting fucked
HB1: You know, PUA, that's exactly what I've wanted to do to you since the day I met you.
While discussing the current state of sperm-bank technology (seriously)
HB2: You're welcome to make a donation any time you want
Both are 7s. Neither made their comments in a location where it'd be easy to escalate. I'm not even sure if I'd want to escalate, given that they are friends. But the question remains: how do I respond?
