One day, a professor asked his students: "If you had only three days to live, what would you do?"
- Student A: "I would stay with my girlfriend."
- Student B: "I would go back to see my parents."
- Student C: "I would try my best to eat some delicious food."
- Student D: "Professor, I would attend your lecture."
Hearing this, the professor was deeply moved. He thought, "At least there is one student who wants to attend my lecture." At that moment, he was eager to know why the student liked his lectures. So the professor asked, "May I know the reason?"
"Because when we are in your class, we feel that one day seems like a year," answered Student D.
