Nonverbal cues are the messages we send without using words. These can include facial expressions, body language, gestures, and even eye contact. For example, a smile can show happiness, while crossed arms might indicate defensiveness. Understanding these signals is essential in communication, as they often convey more than spoken words. In everyday interactions, nonverbal cues can enhance or contradict what we say. For instance, if someone says they are excited but their tone is flat and they avoid eye contact, their body language may suggest otherwise. Recognizing these cues helps us better understand feelings and intentions in conversations with others, like friends or colleagues.
