Which of the following is a fundamental difference between talking to a person live on the telephone and leaving that person a message?


1. Giving bad news by message instead of in a live call ensures that the person won't be mad at you for it.


2. There is no way to know the person's reaction or response to your information when you leave a message.


3. When you talk on the phone live, you can use hand gestures to help the other person understand your point.
