“ Too many people go through the ceremony of an introduction merely as a matter of duty, without realizing its portent in the matter of friendship and future acquaintance. We have all met the man or woman who nods stiffly in acknowledgment of an introduction, and offers some stereotyped expression of welcome. And we have all met the man or woman who smiles warmly, offers a sincere handclasp, and acknowledges the introduction so cordially that one feels entirely at ease. ”
