Before graduation, the teacher said: "Students, what kind of candy do you like to eat? The teacher will buy it for you." The students said: "Puff pastry toffee!" The teacher said: "Then why didn't I see you bring it to school to eat?"
Students: "Whether this candy comes or not is not up to us. It's a pity that we won't be able to eat it after graduation." Teacher: "Why can't we eat it? I just want to buy it if I want to eat it." Students: "It would be great if I could buy it." Teacher: "?"
Purpose: Everyone has the right to control their own life
