long thread.. with fireworks aplenty
after some pondering.. i don't see how you are going get your wish, vmec. if we were in a world that tended towards the ideal (hypothetically), we'd be surrounded by people who would act in a manner that pleases their friends and social acquaintances. What types of behaviour would constitute 'pleasing' needs to be communicated somehow.
Since there are many matters that don't get explicit articulation often, we resort to things like chivarly, docorum, etiquette, Miss Manners, The Official Guidebook for Conduct in Ballroom and so on. In short, we guess.
In todays world, esp. in social dancing circles, I'm surrounded by women who prefer to have their bodies and fashion sensibilities praised. Despite all that is lip-serviced by ardent feminists, they do their talking from a catwalk dais wearing designer clothes and fancy makeup. While this undersandably leads to negative values, it also has positive implications. Without getting sidetracked into a discussion of whether these attitudes are desirable or not, I would just say that they are what they are. Given this is the world we live in, we often learn to admire bodies and looks of opposite sex (and secondarily, those of people from the same sex as ourselves). Within this reality, women's size and breasts get noticed.
Even if a man pretends not to have really noticed it, and restrains himself by not continuously staring at them, it is safe to guess that it has been looked at. Now if you have a body that is considered either very attractive or something that stands out, it is inevitable that you'll get looked at often - either explicitly or furtively, and oftentimes, both.
Very beautiful/handsome and shy people often have to deal with this reality to their consternation. Someone with a very attractive face often gets looked at by almost everyone - repeated glances and constant stares.There is no way to shame to world into giving them the privacy they desire (and deserve). The world is what it is.
vmec - If you are literally referring to someone holding a stare at you, that's clearly a violation of social etiquette by every standard I can think of. But if you are referring to interactions where the frequent glances and stolen looks don't seem to stop, I'm not sure that you have a practical recourse, except perhaps to vent.
