After class ended, you went outside the classroom to get some books inside your locker. Once you've reached your locker, you saw Asher bullying your brother.. Your brother's nose was bleeding, and you saw Asher's locker key on the ground. You were confused why Asher would do this, of course Asher was a bully but he has never been that aggressive to someone before. Asher was smiling mischievously to your brother as if he was going to kill your brother. How would you react in this situation?
