In our daily life, we always face a problem that what kind of communication way is more proper for the discussion. When it comes to some upsetting or controversial problems, in my opinion, using email and text messaging would be more appropriated than utilizing ways relied on voice. First of all, considering the characteristic of this kind of problem, which would easily lead to emotional expression of the conversation that is not pointed to the problem but the person, we won't have the additional choice rather than using text. Because if someone is giving a response to the things that he dislikes or is not comfortable with, he will be more probably not rational any more and turn to fight back against the debater. Here is an easy example to illustrate this. When I was the leader of a student organization in the campus, I once held a online-meeting via Skype to discuss about whether we should hold a business forum next month. When teammate A said he agrees with the idea and talked about the blueprint as well as its meaning to our organization, B totally disagreed with that claiming that it doesn't meet our purpose and value. Then the discussion turned out to be a quarrel when A feel awkward that he was not accepted by others so that he pointed out how he was unsatisfied with what B did in the last month. As we can imagine, the problem was not solved at all. However, I mark this problem in the email after the meeting and let them demonstrated their idea via e-mail. One day later, B told me that now he could understand the meaning of holding this forum and he apologized to A for his impoliteness. In this case, I think the e-mail plays a crucial role in solving this controversial problem because they can see a whole picture of each other's idea and have a lucid understanding without being pissed off by just one perspective or word. Secondly, I consider the form of texting can give both of us time in response to each other but not to waste time in thinking between the two sides when holding the phone. For an instant, once my classmates and I were have a discussion about whether suicide is rational and moral via the phone, we spent like 80% of the time on thinking and keeping silent because it takes time to come up an convincing example to demonstrate our idea especially we were just having some introductory courses of Death. If we can discuss in e-mail, we can focus more on doing research in the library and collecting idea and opinion which would make a better result. The last but not least, the text-form is easier to be recorded and communicated to others. When a teacher try to remind their student to hand on the paper next Monday, I think he will choose e-mail and message because this message which will be regarded as annoyed one by students would not be forget if students can check it in the form of text and the student can forward the mail to inform everybody who did not attend the class as well. We cannot conceal the fact that the un-instance of the message e-mail will lead to disagreement with a specific point in the discussion which can not be solved instantly so that it may be an obstacle of the discussion. However, taking all the aspect into consideration, it's still a good way to communicate with e-mail or text messaging rather than voice message especially when voice would lead to misunderstanding when people are discussing upsetting and controversial problems.
