During the fourth period, the math teacher felt a bit tired and asked the students: “In the next period, if anyone feels tired, please raise your hand, and I will let you take a break.”
The entire class raised their hands except for one student. The teacher and classmates were surprised, and she asked, “Why didn’t you raise your hand? Do you want to stay for the fifth period?”
The student replied, “Dear teacher, I no longer have the strength to raise my hand. Please let me go for this period!”
