Satirizing others is not a positive and healthy behavior that can promote good interpersonal relationships. It may cause conflicts and unpleasantness, which is not conducive to the creation of a harmonious atmosphere in the class, so it is not recommended to use this method in the class group. For the situation where classmates are always late, it is more appropriate to communicate in a friendly and constructive manner. For example, you can talk to this classmate in private and gently remind him of the inconvenience that being late may cause and the impact on class order; or you can say in a more tactful and objective way in the group: "Recently, I found that some students occasionally show up a little late. I hope everyone can be as punctual as possible.Arrive at school so that our studies and activities can be carried out in a more orderly manner. ”This not only expresses timely expectations, but also does not specifically accuse someone, which helps to maintain a good class environment.
