You pick out the weak link of the group, a meek girl sitting beside the wall trying to blend into the brick.
You walk towards her desk and crouch forward until she can't avoid your eyes.
You stand like this until tears bead in her eyes and your own begin to water from the strain.
You ask the question again and she mumbles out a misinformed answer.
You move on with the class and she complains to the prof about you.
