A symbol can take on a new meaning if at least two people agree that it will have that meaning for them. A romantic couple, for example, might use the phrase “I’m sleepy” to indicate interest in lovemaking. Social groups, such as fraternities and sororities or sports teams, might use a handshake, a password, or an article of clothing to set themselves apart from others. We cover verbal and nonverbal symbols more deeply in Chapters 4 and 5.
