Club activities

Hi, students from STAB and others.

I went to school this afternoon. I was there to make sure that the students cleaned up and cleared up after their club activity was over.
There were only 7 students who helped to clear up. What happened to the other students. "Mana boleh!"

How could other students leave the place without helping?
Students, be responsible.Please.

Your teacher,
Mr. Woon
