Another caution is that when we post something to a lot of people who read it. Therefore, before you post a good idea because it will affect many people. It affects our own. Meanwhile, the fact that talk or chat together, we did not see that maybe we do not know it by posting multiple messages that do not have adequate reliability in the Internet. Therefore, we should use common sense to believe or not believe in what we do not read. The post is just like saying that. Before speaking before posting it is yet to be released, but when the post said, the catering, they are irretrievable. And most importantly, do be careful because it is not a private area, but it is a conversation that everyone can recognize.
