Their little tiny purpose in their little tiny lives are to Show The World How Wrong You Are. And make you feel like shit, as an added bonus. You cannot argue facts with them, because they will simply twist them or throw in bits that are irrelevant to the argument. Better to just growl for a minute and move on, or block them. You have better things to do, dear lady!
