I'll try to translate a little of the dispute, the two boys from what I understand, are brothers and when they get home the father asks to see their report cards, where the boy with glasses got good grades and the other got bad grades or even repeated a grade. And the father disciplines his son who got low grades and says "I don't want to do that either, but are you going to repeat the year again? And now you're lying to me" he says that the boy lied because when he asks how many beats he took the other time he says he took less than he actually had. And his brother, angry with his good grades, beats the younger one. That's the part I understood. And sorry for the bad English hehehe
