This book includes: Asking for leave: An employee hasn't been to work for two days. When he came to the company on the third day, the boss complained, "e;What have you been doing these two days?"e; The clerk replied, "e;I accidentally fell into the street from the third floor window."e; The boss angrily asked, "e;Does it take two days to fall from the third floor?"e; Wisdom: In the workplace, it is not terrible to have a passive situation. After all, people are not all-rounders. However, letting the bad situation continue to deteriorate is a matter of responsibility. Just like the above humor, since "e;I accidentally fell from the third floor to the street"e; (whether the reason is absurd or not), why not ask for leave in time? "e; Good insight"e;: A businessman and one of his friends were invited to a professor's house for dinner. During the dinner, a guest asked him if he liked Shakespeare. He replied, "e;Yes, but I prefer whiskey."e; The crowd remained silent. On his way home, his friend said, "e;You are so stupid. Why did you mention whiskey? Everyone knows that Shakespeare is not wine. But a kind of cheese. "e; Wisdom: When our ignorance is discovered by others through ourselves, the result is tragic. What is even more tragic is that we use our own ignorance to educate others' ignorance.
