Faiy no.19 :The chat has both advantages and disadvantages. For example, it is useful to be able to make those who are far away or overseas talked to communicate but the sin is the same. I say do not make sense without seeing the speaker or a discussion. Could be interpreted wrong, as one would say. But the meaning back into another one. The more people are addicted to chat, it can be forgotten that we should talk to the person beside you. I went to chat to cause accidents. Chat bad could cause misleading.
