As a younger sister, you grow up

Looking up to your older sibling for all your life

trying to learn from them.

Seeing what they do wrong.

Until you finally approach to the age,

were you stop arguing

and fighting.

I see that happen with other people.

Them and their siblings hit a certain age 

a certain maturity, 

and they are on peaceful terms.

For me that on lasted about 2 years

When we were both teenagers.

Then I started to see how in every story

he made my mom the villain.

He blamed her for everything;

Praised my dad.

Every time he talked to me he'd criticize my mom.

I try to understand that we had the same parents but different childhoods

But I can't help but hate him

for hating her.
