Is AUTHOR wrong in the post ? POST : I am currently living in a step-family. There is me, my mum, my step-dad, my two stepsisters and my little brother. I am the oldest child in the household and always voice my opinion when I feel like the parents are being unreasonable with my siblings. 

They always yell at me when I try to stick up for them(only when I think they are being unreasonable) but I think that they need to be told they are being unreasonable. 

I don’t feel like my mum is fair to my step sisters and I feel like she babies my little brother (he’s 9) and never tells him off but she is always telling my step sisters off for the smallest of things. This is when I say something. 

For example, my step-sister came home yesterday really excited because she had just learned a new skill is trampolining and told everyone. My mum didn’t sound excited whatsoever for her and said “what do you want, a medal?”.
