Feast Day of St. Julian the Hospitaler,
a patron of hospitality, who has long comforted such travelers as circus performers and other traveling entertainers. C. E. Humphry's Manners for Women (1897) offered readers advice that sometimes ranged from verbal one-upmanship and polite backstabbing to euphemistic pleasantries: "Years of mingling in polite society are necessary to its full development, and though a delicate sense of what is due to others is the very essence of tact, it is never quite perfect without a knowledge of the gentle art of snubbing. ... The 'retort courteous' loses none of its point for being courteous, and how agreeably it compares with the bludgeon style of warfare of some fair warriors."
