This is not the godfather's fault.

In other words, as a father, if you have children, you only care about their food, clothing, housing and transportation, and don't give them strict education. If the child makes a mistake, it is your dereliction of duty as a father and your fault as a father.

The laziness of a lax teacher.

As a teacher, if you don't educate your students well, your teacher is lazy and you are not conscientious.
