Expressions are vital forms of communication that convey emotions and intentions without the use of words. They can be verbal, such as tone and inflection, or nonverbal, like facial expressions and body language. Understanding expressions helps individuals interpret feelings and reactions in social interactions. Facial expressions, in particular, are universal indicators of emotions such as happiness, sadness, anger, and surprise. They play a crucial role in human interaction, allowing people to connect and empathize with one another. Mastering the art of reading expressions can enhance personal and professional relationships.
