Decide not to press your luck.

As you stand there, holding Professor Porter's shoulders, you can't believe that she's going to let you retake the midterm!

"You'll let me take it tomorrow at ten, right?" You don't have anything tomorrow at ten, and the additional day will give you a chance to sleep off this hangover.

"I'll let you take it over tomorrow at ten," Profesor Porter repeats in that same disjointed manner.

"Thank you, Professor Porter," you tell her as you step back. As soon as you do, a confused look comes over her face. She shakes her head, as if waking up.

"Yes, well...I don't give second chances often, Simon, so don't blow yours. Be in my office at ten o'clock sharp tomorrow morning. If you're so much as thirty seconds late, you'll receive a failing grade for your midterm. There won't be a third chance, I promise you that!"

"I'll be there, Professor Porter, I promise!" You quickly leave, not believing your luck and not wanting to give Professor Porter a chance to change her mind.
