After years of exercising the art, I've learned to detect immediatelly whether a girl finds me attractive or not. But the more I've analyzed it the less I've understood it. I know many of you have mastered the same skill and thus I once more seek your wisdom.

Of course IOIs follow the immediate encounter but during first few seconds you can tell how hard it'll be to win her over. Personally I've come to the conclusion that the phenomenon is submission. She typically acts in the similar way female animals do when they give in to an alpha male. A bit like emphasizing their worthiness.

But that's just my guessing. Any of you, fellow Sedditors, have a better explanation?
