Some audiences are easier than others. People may be falling asleep after a meal or too raucous after cocktails. Others might appear bored to death or do not laugh at your jokes. There might even be a heckler, someone who challenges statements and will not wait for the end of the lecture to get answers. On the other hand, everything could go smoothly during the presentation, but you undercut a positive impression by a poorly handled question-and-answer session. Preparation can help you manage these situations.
