A university student recently shared a story about attending a colleague's dinner. The supervisor told everyone to contribute 200 yuan each, but left before the dinner without paying. The five colleagues ended up paying 200 yuan each. Many colleagues felt that the supervisor was being hypocritical, but the supervisor explained the next day that it was an exception. 

Online, many people expressed anger, suggesting that supervisors should not be invited to future gatherings to avoid similar situations. Some also pointed out that as employees, they strive to have good relationships with their leaders and colleagues, but certain actions by leaders can be disappointing. 

The author believes that as young professionals, it is important to actively learn how to communicate effectively to improve interpersonal skills. However, some young people lack tact and often exhibit three poor behaviors in social interactions. 

Firstly, they mock or laugh at others' shortcomings and weaknesses.

Secondly, they gossip, complain, and criticize others, creating animosity among colleagues and leaders. Lastly, they boast about their income or assets, lacking humility. In conclusion, it is important to consider these behaviors in the workplace and strive for better communication and relationships with colleagues and leaders.
