案例分析 Peter is the general manager of an American company in China. Recently, Jun Chen, one of the Chinese managers made a mistake at work that caused some difficulties that required a lot of effort to fix. Jun Chen was very upset about what had happened, and came to Peter’s office to make a formal apology. Jun Chen went into Peter’s office after being told to, smiling before he spoke. “Peter, I’ve been feeling very upset about the trouble I’ve caused for the company. I’m here to apologize for my mistake. I’m terribly sorry about it and I want you to know that it will never happen again.” Jun Chen said, looking at Peter with the smile he had been wearing since he walked into the office. Peter found it hard to accept the apology. He looked at Jun Chen, and asked, “are you sure?” “Yes, I’m very sorry and I promise this won’t happen again,” Jun Chen said, with a smile even broader than before. “I’m sorry I just can’t take your apology. You don’t look sorry at all!” Peter said angrily. Jun Chen’s face turned very red. What are the different interpretations for a smile by the two in this situation?
