One day, a man came to the office very late. Seeing him, the boss was surprised and asked, “Why did you come to the office so late today?” The man said very calmly, “Sir, you always tell me to come carefully!” The boss said, “Yes, but why are you so late when you come carefully?” The man smiled and replied, “Sir, I followed your words to the letter. I walked very carefully on the road, I crossed the car very carefully, and even entered the office carefully. That is why it took a little longer!” The boss was silent for a while and said, “From tomorrow, you will come carefully, but be on time!” Hearing this, everyone laughed.
