Duty to others/country is a must!
Doing this is also make a huge effect to our school and our country since cleanliness always come first. This help me as a scout and as a student because this help my co-students too.
Every end of the class, we stay the school to help cleaning and guarding the school. So basically it's normal everyday.
We don't know how many numbers of students exactly but this helps our school to keep from the harm and dirts. In this duty, we helped the students, teachers, principal etc.
I learned a lot about this since it really feels good to be helping to keep the school clean. I will do better by working more harder.
