Comity

comity \ˈkä-mə-tē, ˈkō-\ noun: 1 a. friendly social atmosphere; social harmony {group activities promoting comity} b. a loose widespread community based on common social institutions {the comity of civilization}

Etymology: Latin comitat-, comitas, from comis courteous, probably from Old Latin cosmis, from com- + -smis (akin to Sanskrit smayate he smiles)

There should be a genre of humor called “the comedy of comity.”
