This is a very tough and dangerous area to generalize in. But one thing I've noticed amongst the women I've known is that as a rule they have more of sense of social context and background than men do, and they keep track of that (changing) context on a continuous basis. So when they say something, they are thinking of it in the particular relevant context. Men typically don't (except when they are involved in certain kinds of competitive situations, e.g., two guys vying for a promotion where they work; then they're comparable to the most delicate seismograph when it comes to extracting informormation from what someone who might know something about the situation is saying). So often when a woman says something to a man, she may well be assuming that he can see what she's saying against the same vivid picture of background social relationships that he does. But I know for an awful fact that I don't do that, which winds up with me missing the point, leading to frustration on both our parts: me thinking, c'mon, you're expecting me to be a mind-reader! and her thinking... how to put it delicately?... uh, why is Bob so dumb???
