sky rocket in flight afternoon delight

I am sick as a dog, but I can't take the day off because all the other teachers are sick, too, and half the kids.

In retribution, I'm making the kids run the class, which they hate. I'm coughing a lot, and before I hand back their papers, I'm licking my thumb "for traction" and smear it all over their papers. But worst of all, I'm speaking in my tiny sick voice, so that they have to be quiet and still in order to hear the lecture.

Revenge? Revenge is sweet.
