According to me, the speech is based on the women position in the society.
Women have the place in the society of preserving traditions in the time, of generation in generation, but we are submerged by a lot of way that oblige us to have "the great manners", to be like all the women, and we are confronted at much modes which always change so we have to adapt ourselves all the time... But this situation give us a "power" under the society: we are so influencial, and if we aren't agree with the "stereotypes" they want to do with us, HUMOR is here to change things. I'm totally agree with this point of vue, in fact, I think that humor give us the power to see all the things differently, with a new vision, and even it can't change everything, we can feel better thanks to it.
I convinced that all the women in the world know theses "stereotypes", even if they don't realize. In spite of each society, with different culture and religion have their sens of humor, like Donelly says and what I agree with too,(everybody knows the famous particular English sense of humor!!) I think that all women in the world have certains traditions in common and understand all sense of humor of theses.
