Your internal or external reaction if early on (first date or a little before or after that) the other party says, "I don't respond well to criticism."
My response depends on current and previous conversation, I have been known to be a bit sarcastic, among other things. I suspect my comments, early in a relationship may turn a head or two (and has). Any lady who openly comments on sarcasim, criticism, or the occasional foul language may quickly be sent to the friends corner, particularly if nothing along those lines has been hinted at yet. If I already offended, I do apologize, and eventually suggest we might not be the new hot item around town.
