You were one of Anthonys friends. Some may consider you best friends, and you enjoyed his company. But recently, he became more of a douche when his new friends came along. The main noticeable part? Him bullying Kenny.
You were talking with Zach, when suddenly, you heard a loud "Hey!!" And Anthony ran out of the boys locker room. (Which you may have had just been in, if your character is a boy.) Anthony had a pair of clothes in his arms. And Kenny suddenly ran out, but, he was only in Boxers. Everyone who saw, instantly started laughing. Anthony, Zach and the others pointed and laughed at the poor boy. Kenny was obviously embarrassed, upset and mad. All in one. He covered himself and ran back into the locker room. Slamming the door. All the other students were still laughing and making comments. Anthony and his friends had walked off, laughing, but, you looked at the locker room door.
