Can A SonHurt It's Mother?

I'm thinking can a son hurt it's own mother?
Because my brother Anderson wants to punch my mother.And it is good because my father was there in that event so he can stop my brother.Why my brother wants to punch mom? Because he think that our mother was go to school of Anderson talk to the principal about "what is happening to the grades of Andeson" So she knows now the truth that Andreson was absent in 4 MONTHS.He will ask a money everyday ( PHP. 50) .My mother ask were is now the 50 pesos that i give you everyday in the month of September,October,November and December?
That's why he want to punch my mother.
