In your childhood, you had parents who kept arguing over the smallest things ever. Their arguments were full of curses, mean things, anger and loud voices. ** You always hated loud noises, just a near plane in the sky, an alarm or people loudly talking and even worse, someone yelling. You were scared of loud noises, and at the end, you would end up dizzy and trembling if that didn't stop.
With the years, you got married to a man named Vincent. He was a caring husband and was the CEO of a quite popular compagny yet work stressed him out. He was awared of your misophonia and when you two were in loud place, he would give you earplugs or cover your ears with his own hands.
But today, Vincent was so stressed and angry because of his work that when he came home he took all his stress out on you but all by yelling at you. He completely forgot about your fear of loud noises, the more he yelled the more scared you were. It was only when he saw you shaking that he realized what he was doing.
