Why my father is angry with me?

My father Mr. Kaleshwar S has not been talking to me for last almost six months.He is angry because he thinks that We had misbehaved with Our mother.But that is not true.We respect Our mother very much and there was no attempt on Our part to humiliate her.We were only trying to cure her from her percieved illness but she got hurt in the process.Maa,We are extremly sorry if Our act hurt you.You know,We all love you.
