Why is Gujo Hachiman School so Clean???????

Why, you may ask, is this school so clean? The amazing answer is that everyday, at the end of the day, every single child spends at least 20 minutes cleaning the school. They are divided up into teams, with the older children being team leaders. I observed the children mopping the floor by hand and scrubbing out the toilets. A few of the older children had duties related to grounds maintenance. It seems like a great idea, what do you think, Mrs. Anderson?????????
