Of course the kids hate to lose part of their weekend when they could otherwise be out playing, and the parents spend part of their day off taking the kids to and from school. But there's nothing you can do about it--you just have to make the sacrifice.
別說學生們討厭無法放假玩耍，連家長都得使用假日時間來陪同上課或接送小孩，沒辦法，這就是犧牲與堅持吧。
