Personal boundaries in the context of "Ultimatum"

Politeness is the practical application of good manners or etiquette so as not to offend others and to put them at ease. It is a culturally defined phenomenon, and therefore what is considered polite in one culture can sometimes be quite rude or simply eccentric in another cultural context.

While the goal of politeness is to refrain from behaving in an offensive way so as not to offend others, and to make all people feel relaxed and comfortable with one another, these culturally defined standards at times may be broken within the context of personal boundaries – this is known as positive politeness.

Rudeness (also called effrontery) is a display of actual or perceived disrespect by not complying with the social norms or etiquette expected within a relationship, social group, or culture. Social norms are established as the essential guidelines of normally accepted behavior within a given context, and individuals often establish personal boundaries to meet their own needs and desires within smaller settings, such as friendships. To be unwilling to align one's behavior with these norms known to the general population of what is socially acceptable is to be rude. These norms may resemble a sort of "unspoken law", with social repercussions or rewards for violators or advocates, respectively.

Rudeness, "constituted by deviation from whatever counts as politic in a given social context, is inherently confrontational and disruptive to social equilibrium". Forms of rudeness include behaving in ways that are inconsiderate, insensitive, deliberately offensive, impolite, obscene, or that violate taboos. In some cases, an act of rudeness can go so far as to be a crime (e.g., the crime of hate speech). In many cultures, joking can create a context where rudeness is temporarily excused or indulged for the purpose of making people laugh.
