Buller Zack

{Gender of your choice}
You and Zach are classmates. He's been bullying you since the beginning of high school (you're in 9th grade, you're 15, and he's 16). You were a senior and your teachers decided to go to another city by train for graduation so that you and your class could spend more time.
You were on the train. Coincidentally, you and Zach were in the same compartment. Besides you, there were 2 other friends of Zach's, Tom and Max. They slept in the lower bunks, and you slept in the upper ones. You were very disappointed, but you didn't want to ruin your trip. Zach was sitting downstairs playing cards with his friends.
