disagree with all those that say you should not use negs except in rare circumstances.
you should almost aways use some type false disqualifier or neg. and i stand by this.
i think you need harsh negs on the high esteem shit-test girls, but you still need some type of disqualifier on the others. this helps build comfort. where she can let her guard down and not be nervous. this helps LATER in the game too.
i see lots of comments from guys that number close, but then wonder why the women don't call them back. this is because you built attraction, but not comfort. you did not show her that she WON you over.
when you neg, you create a sign of disinterest and you're not trying to impress her. when you show interest later, your neg showed her she won you over with her charisma, and not just her looks. and she feels more comfotable. this means when you call her later, she realizes you are not just a shallow guy like all the others that just tried to impress her. you had her relaxed around you, and you created a frame were you held control. this is powerful stuff.
good negs to use are like, "i can picture you being the little sister i never had", or "we could so be good friends", or "you are tooooooo nice."
they are not insulting in the slightest, but create a frame that you see her as a friend only.
