OK, I am going to continue from the last chapter, and this is when Snape tries to apologise to Lily but is not forgiven by her. Dumbledore also makes an announcement.
The next day in the morning, all the students went to the hall to have breakfast. Snape walked to the Gryffindor table trying to look for Lily. But Lily wasn't having to forgive him for his actions.
"Look, Lily. I am sorry for calling you a Mudblood, I promise to.."
"YOU TRY TO APOLOGIZE TO ME? AT TODAY? WHEN I SPENT MY TIME TO SAVE YOUR GUTS, YOU CALLED ME A MUDBLOOD. DO YOU THINK I WANT TO FORGIVE YOU?" Lily bellowed.
"But I am sorry, I was in the wrong. Can you give me a chance?" Snape asked.
"Okay, not to mention as well, you are obsessed with the dark arts. You are a Nazi and a racist, you are a racist because you called me a dirty slur. And you know what? Too bad, I am not going to forgive you. I am never ever going to care for you. Have fun being bullied by the marauders. Goodbye." Lily snapped.
"Okay fuck you." snarled Snape. Just then, James arrived and slapped Snape in the face.
"You dare to curse at Lily again huh? Get the fuck out you crazy man." James said angrily. Behind him were Sirius, Remus, and Peter.
"Yeah go away Snape." snapped Sirius. "She hates you. We all hate you. No one likes you." Left with no choice, Snape stormed off.
After ten minutes, Dumbledore walked into the hall. He announced, "Sorry for this announcement, but I would like to say something. There is a serious incident involving Snape, James, Remus, Lily, Sirius and Peter. But however, Snape is a Nazi and a racist, he hexed James and called Lily a mudblood when she tried to help him. Thus, James and Sirius are both not accused for their actions. I will reward James, Sirius, Remus and Peter also, each fifty points. So in total there will be two hundred points to Gryffindor. And because of Snape the dickhead, there will be no points for Slytherin this year."
There was a loud applause in the Gryffindor table. The marauders and the Gryffindor students shouted, "Yes, yes, yes!"
Meanwhile there were moans and groans from the Slytherin table. All the Slytherin students glared at Snape with daggers and gave him their middle fingers.
After a few days, everyone in the school started to hate Snape as hell. However the marauders and Lily tried to ignore Snape as possible. A lot of students tried to push him off the staircase, a lot also called him slurs, a lot tried to blame Snape for things he didn't do. But their claims are still believable. Snape learnt his hard lesson. From September 1 1976 onwards, Snape never came back to Hogwarts ever again.
