There is a hint hidden between the lines, which is very common in daily life. Especially in business situations, people who seem to say nothing often have strong dissatisfaction with many things. In this case, speaking directly will make the person more angry. The advice at this time is that you should pay attention to the bottom line they give while listening to each other. We can get more information by looking for clues from people's body language, tone and expression.
Of course, not all time and the implication mean something hidden. Sometimes, people just want to make things deeper. In this case, you need to make sure that you understand that what the other person said is just a common meaning, and there is no other possibility. If you don't pay attention to listening on weekdays, you will miss a lot of effective communication. Therefore, the key lies in paying attention to details, persisting in communication, and striving to improve one's communicative competence, so as to communicate better.
