Raising hands to ask questions is a common practice in classrooms and meetings. This method allows individuals to signal that they have a question or comment without interrupting the speaker. It helps maintain order and ensures that everyone has a chance to participate in the discussion. When a person raises their hand, it indicates their desire to contribute while respecting the flow of conversation. This practice is often encouraged by teachers and facilitators, as it promotes active engagement and helps create an inclusive environment for all participants, including students and attendees.
