In Germany, in contrast with France, friendship is much more clearly a matter of feeling. Adolescents, boys and girls, from deeply sentimental attachments, walk and talk together not so much to polish their wits as to share their hopes and fears and dreams to form a common front against the world of school and family and to join in a kind of mutual discovery of each other’s and their own inner life. Within the family, the closest relationship over a lifetime is between brothers and sisters. Outside the family, men and women find in their closest friends of the same sex the devotion of a sister, the loyalty of a brother. Appropriately, in Germany friends usually are brought into the family. Children call their father’s and their mother’s friends "uncle" and "aunt". Between French friends, who have chosen each other for the similarity of their point of view, lively disagreement and sharpness of argument are the breath of life. But for Germans, whose friendships are based on common feelings, deep disagreement on any subject that matters to both is regar- ded as a tragedy. Like ties of kinship, ties of friendship are meant to be absolutely binding.
Young Germans who come to the United States have great difficulty in establishing such friendships with Americans. We view friendship more tentatively, subject to changes in intensity as people move, change their jobs, marry, or discover new interests.

All forms of sales appeals that are sent through the mails are considered direct-mail advertising. The chief functions of direct-mail advertising are to familiarize prospective buyers with a product, its name, its maker, and its merits and with the product’ s local distributors. The direct-mail appeal is designed also to support the sales activities of retailers by encouraging the continued patronage of both old and new customers.
When no personal selling is involved, other methods are needed to persuade people to send in orders by mail. In addition to newspapers, magazines, radio, and television, other special devices order promotions are designed to accomplish a complete selling job without salespeople.
Used for the same broad purposes as direct-mail advertising, unmailed direct-mail advertising, includes all forms of indoor advertising displays and all printed sales appeals distributed from door to door, handed to customers in retail stores or conveyed in some other manner directly to the recipient.
With each medium competing keenly for its share of the business, advertising agencies continue to develop new techniques for displaying and selling wares and services. Among these techniques have been vastly improved printing and reproduction methods in the graphic field, adapted to magazine advertisements and to direct-mall enclosures; the use of color in newspaper advertisements and in television; and outdoor signboards more attractively designed and efficiently lighted. Many subtly effective improvements are suggested by advertising research.
