Dear Statistics Class,
Tonight is the last night I will stress over you. And, in all honesty, I'm not even stressing that much. I did pretty awesome on your last test, and the final from last semester that you gave as a study guide did not phase me. So yes, I feel confident that our time together will not have been a complete waste of time, but instead, like any relationship, a time of learning and growth. Thanks for taking up my summer nights and weekends and making them less carefree. (In case you can't tell from these words on the screen, my tone is a bit sarcastic.) I will take your final and have that be that.

Sincerely,
Julie
