My mum and my older sister argue a lot but they usually put it down to them being like each other. Maybe that's the case but I honestly don't see the connection. I'm often viewed as a child by both my mum and older sister (i'm 17) so I often get shouted at for trying to resolve arguements which annoys me to no end. Thing is my mum is wrong a lot of the time and usually the arguements involve my sister trying to tell her she's wrong but my mum doesn't listen at all. If it gets to the point where my mum is being blatantly mean and unfair to my sister I'll always step in. Though the response I get from my mum is almost always "don't but in, this is between us!" but I know for certain that my sister needs confirmation that she's not alone in her views. I could never hate or dislike my mum though, it's not her fault she gets like this sometimes. Half the time she's really cheerful. Plays music full blast hahaa but when things get out of hand I'll always defend the victim. So I guess it is essential to argue sometimes but consider both situations and think of the conclusion. If your parents don't listen when you argue maybe it's time to think of a different approach. Maybe you're going about it wrong? My mum often tries to solve things by shouting and that has only ever made things worse. Notice the things that cause your parents to get upset. Crossed arms, raised voice, standing over them, looking away, little alterations.
