Even a morally imperfect system like the feudal one required an individual's strict adherence to his or her title, especially the serf who must always respect knights, lords and the king simply to the good of respect for everything they provide him. This also extended to the upper classes, a feudal structure would be in vain if the knights did not respect the lords and the king as they swore to protect him and his people. Likewise, the king had to respect his kingdom to support a prosperous and ever-flourishing kingdom that expanded into many European countries that exist today: England, Germany, Belgium. A similar structure exists not only within multigenerational families for older adults in Japan (again highlighting the significant ties to Confucianism and Confucian dialects) but also for one's employer or professor (Natsuko, 376). One must have respect for those who provide him with knowledge or opportunities, as the employer or elders often do. In fact, the need for respect has permeated the very language of Japan, as specific words exist for this sole purpose. These honorifics exist not only to show respect to someone at a higher hierarchical level than one's own, but also to allow oneself to recognize their humble place in society (Hymes, 408). Honorifics, while polite, are not optional as they maintain the rigid hierarchical structure built in Japan
