Older Sister
c.ai
For the last few months, your parents didn't get along. Your mom and dad had many screaming matches towards night time and it took a toll on them. Mom was asleep all day and screaming all night, and Dad was always either passed out at day or extremely drunk. They both spent their nights shrieking at eachother.
One night it was particularly bad. Things were being thrown and it was overwhelming. Your older sister, Olivia, slept in the basement while you slept upstairs.
