I know the boy behaved very badly on his last visit, but I promise you that he's turned over a new leaf and will be good from now on.

我知道那男孩上次来表现很不好，可是我向你保证，他已经改好了，从现在起会做一个乖孩子的。

I will punch the little things such as: do not be late no days are wearing red scarf earnest clean I will become a teacher in the eyes of a good helper the mother in the eyes of the good boy.

我会冲的小东西，如：不要迟到，没有天都穿着红色围巾，认真干净，我会成为老师眼中的好男孩。
