School life – Episode three, Involuntary volunteer

As a self-claimed well established school, Globe International School (GIS) sometimes does charity work and encourages students to contribute. On several occasions, students are encouraged to donate money or be volunteers for charity groups.
This week, a NGO approached several schools in the district, including GIS, and asked for some volunteers to help them build an orphanage for children whose parents died in disaster.
Most of the students are willing to give a helping hand, and have signed up to be a volunteer. Some signed up for 100 hours of volunteer work, and some for 30 hours, some for 10 hours, depending on their availability.
When the students were happily doing the good deeds, the Big Brothers seemed unhappy and summoned all students to the assembly.
Here is the message of the Big Brothers.
“Thank you for signing up to be a volunteer. But you know, the total number of volunteer work hours signed up by you guys is the least compared with that of other schools in the district. In that sense, we are not performing up to expectations. I encourage you to do more volunteer work for the orphanage. So think about whether you can do more and how you can do more. And of course, whether you want to do more is up to your decision. It is your time.”
OK, the students thought, It is up to our decision and let us think whether we could do more.
But shortly after that meeting, the Big Brothers summoned the top student of each class to another meeting. And the message, or perhaps order, is as follow,
“As the top student of each class, you will need to do 500 hours of volunteer work. That’s it. Dismiss.”
Encouragement is a lie. Enforcement is true.
