"How are you?" is a common greeting used in many cultures to inquire about someone's well-being. It is often used in casual conversations and can serve as a polite way to start a discussion. The phrase can be answered with simple responses like "I'm good," "I'm fine," or "Not too bad," depending on the person's mood or situation. In some contexts, such as in business or formal settings, the phrase may be used more as a formality rather than a genuine inquiry. People may not expect a detailed response, and it is often understood as a way to acknowledge someone's presence rather than a request for personal information.
