An interpersonal relationship is a strong, deep, or close association/acquaintance between two or more people that may range in duration from brief to enduring. This association may be based on inference, love, solidarity, regular business interactions, or some other type of social commitment. Interpersonal relationships are formed in the context of social, cultural and other influences. The context can vary from family or kinship relations, friendship, marriage, relations with associates, work, clubs, neighborhoods, and places of worship They may be regulated by law, custom, or mutual agreement, and are the basis of social groups and society as a whole.
Philosophy of love is the field of social philosophy and ethics that attempts to explain the nature of love. The philosophical investigation of love includes the tasks of distinguishing between the various kinds of personal love, asking if and how love is or can be justified, asking what the value of love is, and what impact love has on the autonomy of both the lover and the beloved.
Wild boar or wild pig (Sus scrofa) is a species of the pig genus Sus, part of the biological family Suidae. The species includes many subspecies. It is the wild ancestor of the domestic pig, an animal with which it freely hybridises. Wild boar are native across much of Northern and Central Europe, the Mediterranean region (including North Africa's Atlas Mountains) and much of Asia, including Japan and as far south as Indonesia. Populations have also been artificially introduced in some parts of the world, most notably the Americas and Australasia. Elsewhere, populations have also become established after escapes of wild boar from captivity.
The wild boar and boar's head are common charges in heraldry. A complete beast may represent what are seen as the positive qualities of the wild boar, namely courage and fierceness in battle; a boar's head may represent hospitality (from the custom of serving the boar's head in feasts), or it may symbolize that the bearer of the arms is a noted hunter.
In classical heraldry of the late medieval and early modern period, the boar is somewhat rarer than the lion, eagle or bear. A notable example from the late medieval period is the white boar of Richard III of England (1452–1485). The boar appears frequently on coats of arms of towns or cities designed in modern times. More rare than the boar is the sow or female pig (often shown as suckling piglets), found on some municipal coats of arms such as that of Albano Laziale.
