Ex Input:
Person1: Hey Sarah , are you all right ? You look upset .
Person2: As a matter of fact , I am a bit upset . I just came out of a meeting and it didn't go very well .
Person1: What happened ?
Person2: No one would listen to any of my suggestions . Instead , they just kept arguing with each other .
Person1: Who was chairing the meeting ?
Person2: Bob .
Person1: Well , I can tell you from experience that Bob might come off a little strong sometimes .
Person2: That's exactly what happened ! He kept interrupting everyone with his own suggestions and did not want to hear what others had to say . Then he expected everyone to agree with him .
Person1: What was the meeting about ?
Person2: We were trying to come up with ideas to streamline the office's workflow to make it more efficient .
Person1: It's ironic that the meeting was anything but efficient .
Person2: Exactly . I had tons of ideas that I wanted to share , but they just wouldn't let me finish . What should I have done to get my point across ?
Person1: You have to keep things short and sweet . When you get a chance to speak , try not to get into too many unnecessary details .
Person2: Short and sweet ? But what if I have to explain something complicated ?
Person1: You can always bring up the main points during the meeting and speak to those who are directly involved after the meeting . Not everyone needs to know all that information .
Person2: That's a good idea , I think I will try that at the next meeting .
