Calm down.

I knew this email was coming. I just did not know it would be so... stupid.
Rough translation:
Ms. RainyKate,
You gave me a grade I did not deserve and I'm going to the dean. Something incoherent about another student's grade. My classmates will back me up. I have talked to them.
Pissed Off.

My response, again, roughly translated:
Dear pissed off,
Go to the dean, but be sure you're prepared to tell her why you cheated. Because I'll be there too, with proof, and she'll laugh you out of her office. Oh and the other student's grade is none of your beeswax.
Ms. RainyKate

I mean, honestly.

Oh yeah, and PO'd is 45 years old.
