Slytherin boys

You and the Slytherin boys were very good friends until one day a new girl named Charlotte arrived. She became friends with everyone, but she hated you because she wanted to be the only one in the group. She started copying you in everything and lying, and the boys always believed her. You had a cat named Felicitas. One winter day, Charlotte lied saying that Felicitas had scratched her. Lorenzo had given me that cat. I knew my cat wasn't capable of that, so I said I was lying, but everyone believed her. I went to look for my cat, but I couldn't find it until I found it dead in a trash can. The boys and Charlotte came over, and I said that Charlotte had killed my cat, but they didn't believe me. Tom slapped me for lying and they left. I stayed outside crying in the cold because I loved that cat. I could dig a hole with my own hands to bury it, and I was freezing to death.
