(Y/N) POV
I was walking in the halls. I saw some kids staring at me. I give them the stink eye. They all look away. I'm the substitute teacher if anyone is sick. If I'm not then I am the detention teacher. I was walking to Error's office. I was very angry with him at the moment. He fucking threw away all the paper work I had to grade for Science. How do I know this? Well I was walking into the Science room and see him tear the papers to shreds. I was walking the other direction. I know he likes to joke around but that was way too far. It took me hours to grade all that.

I stormed into his office. "Hey toots." He waves lazily. "Don't 'hey' me Error. Why did you do that?" I give him the death glare. "Did what?" Is this bitch really doing this right now? I give him the look. "Don't fucking play dumb. Why did you destroy the science homework?" He smirks. "Watch your profanity." He points at me while getting his ass of the chair. "I don't give a shit. Now answer my fucking question you son of a bitch!" I yell at him. (True story I said all of this to one person each day in Social Studies. I said it out loud and my friend started laughing.) He backs up a bit from me yelling at him.

"You know I like to joke around (Y/N)." He said with that smug look on his face. "Well that fucking joke wasn't funny. Do you know how long that took to grade? You can grade people in the middle of class. But not for me. I actually have to sit my ass down and grade millions of papers." I said silently but loud enough for him to hear. "Sorry." "Sorry is not gonna cut it Error. Now I have to fucking see Miss. Temmie about this. Thanks for making my job easier." I storm out of his office. I mutter insults to him while on my way to the office. "Fucking retard that doesn't know what he is doing." I mumble. I then enter the office.

Error POV
I enter the Gym. Then I see everyone walk in. "Well did you do it?" Everyone asks me. "Yes I did." I said with a proud face. Everyone cheers except for 4 students. Odd. Every student hates (Y/N). Well no matter. (Y/N) probably not coming to school in a few weeks because of that assignment. It was the majority of the students grade. "Ok in honor of this we will play dodge ball. And you can pick your teams." Everyone cheers except for those 4 students. Wonder why they are like that.

(Y/N) POV
This is just fucking great. I can't teach for 2 weeks for something I didn't do. I went into the Science room to grab my stuff. I grab my bag, my jacket, and my phone. "Stupid Error." I mumble. I put on my jacket and put my phone in my bag. I then walk out of the room. Then I see Error in the corner of my eye. I groan and walk away from him while texting my kids. 'I'll be home early. I love you both.' I put heart next to the message. I put my phone in my bag. I then hear running. I walk a bit faster out the door. Then I see Error walking next to me from the corner of my eye. "So how was it?" I growl at him. I was now in front of the entrance of the school. "Fucking great. I love getting 'suspended' from school for something I didn't do. Now leave me alone." I said getting out my keys. I said the last sentence a bit quieter and filled with sorrow. Obviously Error didn't hear that.

"Aww I never heard you so quiet before. Maybe if you were like that students will actually like you." I open my car. I felt my eyes get watery. "I get it. You are a liked teacher. Now leave me alone." I drive off. I drive to my house. I parked and got out of the car. I open the door and got greeted with my twins. Mike and Lucy. (If these are your names then you can change them.) "Momma/Papa you are home." They both hug me. I hug them back. "Hello my lovelies." I let go and make the food for them.

I gave them alphabet soup. They eat up. "Hey momma/papa how come you act different to your students after they get detention?" Mike asks. I sigh. "At first I act mean to them so they don't break rules. If they are good kids I treat them nicely. But if they get detention I give them a lollipop and ask them to not do it again. That is my reason and explanation. Also I might be getting a new job as well." They widen their eyes. "Ok." I smile and pat both if their heads. They both giggle and smile. "Don't worry I'll get one soon." I walk into the living room and read.
