I'm going to pick a fight with a student
Why would you pick a fight with a student?
It's obvious he is a troll and no honest friend can be such a bad loser.
You should try to just ignore your issues with the student. It seems wrong to actively seek to start fights with someone especially a student.
He started the fight first.
It sounds like you started it though, and you should be the one to end it. Just move on and ignore the student.
