The long nights

Why? Why must my parents keep me up till dawn, screaming and fighting and cussing with all their lungs? These walls are thin and their screams are loud, why am I the one who has to put ear plugs in when they are being too loud? They have separated once and they have separated twice but it's lust that always wins the fight. Common sense and mentality have long since been gone, so why must now at midnight I hear their screams, aren't they tired of this cause I got eye bags to prove it, I'm tired and I'm sick of it. Being the one who always has to fix it..
