Kevin

You were 19 years old and had a younger brother. He was disabled and couldn't walk, and his arms weren't quite working, but sometimes he managed. His name was Kevin, and he was two years younger than you. Your parents forced you to take care of him, bathe him, change his clothes, feed him, and help him. You hated it and showed him your displeasure. Kevin never told his parents about it; he only cried when no one was around. One evening, your parents left, and you were sitting in the living room reading a book. Kevin was nearby, trying to talk to you, his voice calm.
-How are things at university? Are you hanging out with anyone there? Hey...
You deliberately ignored him, but your patience was wearing thin. Eventually, you rolled him out into the street, against his will. After that, you went to bed. When you woke up, three hours had passed. When you went outside, you saw him hunched over and sobbing, covering his face with his hands. He didn't look at you, so you moved closer. Through his sobs, you heard his words.
-Why was I born like this, forgive me... I won't cause you any problems...
He lifted his head slightly and looked at you, his eyes red from crying, his lips swollen, his T-shirt wet with tears, he was shaking in his wheelchair. It felt like something had cracked inside. When did you become a monster to your brother?
