Here is what to expect from a biology teacher : One day you might show up to his class, but not him, and then open his email in which he excuses his imaginary substitute for not being there.

Teacher: manifestement, mon remplaçant ne s'est pas présenté ce matin
His student: C'est correct, on vous attend demain
*teacher doesn't even have a class tomorrow

“Dude, his stuff is pretty out there but he’s still pretty Finance Punk.”
