I'm going to put the brightness all the way up when it was night so then the guy sitting next to me wouldn't be able to sleep
Why don't you want him to sleep?
He's a jerk.
That is very wrong to bother other people like that. It's rude to interrupt someone's sleep like that.
Nah, I'm doing this so he'll leave me alone and to teach him a lesson.
If you want him to leave you alone you should just tell him to go somewhere else.
