Your feedback is the way you respond to your audience's questions, comments, or reactions. You can use your feedback to show your respect, appreciation, and openness. For example, you can use positive gestures, such as smiling, nodding, or clapping, to show that you are happy and grateful for their input, negative gestures, such as shaking your head, frowning, or sighing, to show that you disagree or disapprove of something, or neutral gestures, such as shrugging, raising your hand, or tilting your head, to show that you are unsure or curious about something. You can also use verbal feedback, such as thanking, acknowledging, or answering them, to show that you are listening and interested in their opinions. However, be careful not to interrupt, ignore, or argue with your audience, as this can make you look rude, arrogant, or defensive.
