Well, I pointed out odder parts of my thinking processes for
   similar reasons you mentioned about men and the nail: I know the
   obvious answers already (that women want to establish a
   relationship between themselves and the situation they're in
   with regards to the nail; that's how women seem to tend to work
   afaik - and that she's not complaining about the pain but rather
   discussing it, as a stress reliever and as a way of continuing
   and an opportunity to deepen an established relationship with
   the partner.. because the nail will be gone eventually but is
   their relationship what she thinks and does she know him as well
   as she thinks he does - and stressful situations and the
   partner's reaction are indicators of the depth of the partner's
   understanding of their mental/emotional processes - ie "can you
   read me or are you blind to me?"). How he handles this situation
   is considered to be indicative of how he handles other
   situations, not involving nails. I'm not* really saying that men
   only have a few emotions... even if that's how I worded it.*
   Rather, the way that women talk about and understand emotions
   and relationships is a system that is entirely foreign to a good
   portion of men in the population. There's a nail in her head.*
   Guy thinks, "Get rid of the nail. Done." There's a nail in her
   head.* She thinks a lot more thoughts than just the nail. Of
   course some of it is based on a cultural illusion: that
   mindreading is even possible by reading clues and signs.*
   There's a whole science of body language, word cues, response
   mechanisms within a feminine culture that just... isn't really
   there in "man world".* Man culture has a more limited
   expressiveness in this regard. But mindreading isn't possible -
   not really; yet, determining "intent" or trying to discern,
   "What did you really mean by that?* There's more than what you
   said - it's HOW you said it.. " is a huge part of female
   culture. It's barely there in typical male culture.* This is
   what I mean by limited emotional stuff with regards to men. Yet
   it's not emotion vs reason. Reason is pushed by the amygdala -
   pushed by emotion.* It's not a separated system.* Pure logic and
   reason in a human results in perpetual indeciveness, as they've
   found with people with brain damage to the amygdala.* Without
   the emotional push, you can't make conclusions without GREAT
   difficulty. See:

   +[2]strontiumXnitrate +[3]Jack Butler I also know that I have no
   idea what I'm talking about and that which I do understand is
   hard to explain.* If this stuff was easy to explain, understand
   and be understood, I doubt there's be an "it's not about the
   nail" issue to begin with. Wouldn't it have been solved long ago
   if it was easy? I'm utilizing stereotypes here.* All women are
   not this way.* All men are not this way. Perhaps NONE are, and
   I'm just talking out of my hat.* All valid possibilities.
