The secretaries who were stationed outside President Mo's office noticed the recent change in their boss.
At a certain fixed hour, Assistant Shawn will step out of the President's office and reminded the secretaries to not let anyone disturb President Mo for about half an hour.
No one knew why Assistant Shawn gave that order, or why President Mo needed a half an hour break when he used to be a workaholic. However, the secretaries noticed something.
After that thirty minutes break, President Mo's mood would improve greatly.
For example, a week ago, a manager had made some mistakes on a very important proposal, causing President Mo to be in a very bad mood. Anyone who entered his room would be sent out crying. Even Assistant Shawn suggested everyone be on their best behavior if they did not want to provoke their boss's anger.
However, his bad mood miraculously disappeared after that half-hour break.
