Why do you say, "When communicating with strangers for the first time, you must pay attention to avoid talking about trivial matters of life and family"?

Try to avoid talking about personal problems when communicating with strangers, because most people are wary of people they don't know. If such issues are involved too much in the conversation, the other party may think that you are impolite and want to stay away from you, or that you are uneducated and don't want to talk to you again. But strangers are not exactly like this. Some optimistic, cheerful and free-spirited people are not sensitive. They will chat with you, talk about trivial things, talk about everything and say nothing. If you talk to them about family chores, they may think you are honest and heartless, and maybe you will become good friends in the near future.
