Short Horror Stories So I Do Something With My Life/Creepypasta

Story nr 2: I like your laughter

   I loved working at the psych ward. Most of my patients were either nice or incapable of harm. At least the ones I worked with. Of course, I was just a simple nurse and I didn't really treat patients, but my visits were often delightful.
   Others told me I was naive, but I prefered to call myself positive and friendly.
   My favourite patient was definetly Isabella. She was a 9 year old with sociopathic tendencies. She killed her mother with a brick after finding out they gave up on finding her lost sister, and her father, who didn't know how to deal with her, locked her up in the pantry till he sent her to our psych ward.
   Every time I visited her, she would throw me a sweet smile and enthusiastically talk about how her day went. I warmed up to her quicky.
   One day, I went to her room to change her straitjacket because it was dirty with her food and drool. As I was changing her, she would enthusiastically babble on about her food. I patiently listened to her, smiling. As I fed her, she asked me: "Can I hear your laughter?"
"Sure" I said and tried to laugh as sweetly as I could. She liked it and laughed herself.
   I finished feeding her and started to comb her golden locks. They were soft but badly cut and I was not allowed to bring scissors in her room. She was a good manipulator. Her first nurse made the mistake of warming up to her and while cutting her hair, she let Isabella hold the knife. After Isabella studied it well, she tried to break out by stabbing the wood-blocked windows.
   I was scared to first work with her but as I warmed up to her, I felt more comfortable. After I combed her hair, I said goodbye to her and left. Before closing the door, I heard her struggling and a wierd chewing sound but I just thought she was trying to get comfortable in the new straitjacket.
   For the rest of the day, I had to work with other patients, mostly a few old people or schizophrenic children. I had to check up on Isabelle one last time to feed her dinner. After picking up the food, I slowly walked to her room. The psych ward at night was always a bit uncomfortable, but I kept my composure.
    As I opened the door, I saw Isabella sitting on her knees with blood running down from her mouth and chin onto the floor, mixing with tears and sweat. Under her mouth was a strange object, bleeding and making a pool of blood. I was stuck, frozen in horror. Was that.... No way... Her tongue??!
   Isabella turned to me, smiling happily. Her mouth was slightly open and I could see her teeth soaked with blood. The blood had soked her straitjacket. Tears of pain ran down her face, but she was smiling happily. "Eyh ook, ay oungue ih on he hloor!"(Hey look, my tongue is on the floor!) I could feel my head getting lighter. I screamed as loud as I could, making Isabella smile wider. The last thing I remember was Isabelle getting up and running towards the door, blood tailing behind her, running down her chin and neck.
*  *  *
   Isabella ran out of the room. She smiled widely, seeing that there were no other nurses inside the psych ward. She ran as fast as she could and burst through the front doors. She could hear people screaming in alarm, shouting her name. That made her smile wider. Running, running, running. That's what Isabella remembered in her first few days outside of the psych ward.
   She sat behind a dumpster and pried open her straitjacket with her bloody, sharp teeth and found a small sheet she managed to put on her body.
   After a few months, Isabelle walked in the streets of the small village, enjoying the company of people. Their voices filled her head, making her feel content. Laughter. She could hear laughter. A small kid was laughing. A little boy laughing with his father. She looked at him and felt a pang on her chest. Sister. Laughter. Sister last memory, laughter. She followed the boy home, but she couldn't get in. Smiling, she found a small window and sat under it.
   As soon as the sun set and bedtime approached, Isabella opened the window and climbed inside. She sat on the bed and looked at his face. She got closer. His mouth was slightly open. Isabella reached for his tongue. The kid couldn't see clearly and started to scream. Isabella bit as hard as she could on his tongue. The taste of blood filled her mouth. So tasty, so metallic. The smell of blood filled her lungs and giving her a headache, but still nice, she thought. When it came off, she grabbed it and  painted on the wall, Isabella likes your laughter. Giggling she wished the kid night-night, and ran out into the darkness, leaving his worried parents scream out of horror.
"I should do that more often" she thought, giggling and hopping her way to the village.
