Oh, no, no, no, that won't do at all." Harshwhinny presses the sole of her foot against your face, her big toe tracing little teasing circles beneath your eye. "I'm afraid you forgot to apply the Hermitian operator. And your dirac notation is sloppy." "But… I thought I had it." "You thought wrong. Try again." She places her foot against the back of your neck, forcing your head closer to your textbook, upon which a half-dozen pages of Physics problems are scattered. "Can I just…" You crane your neck, trying in vain to reach her sole with your tongue. Harshhwinny cackles, drawing her foot just out of your reach. "Ah ah, remember what I said? Finish homework first, *then* you get to worship my feet." "R-right…" "Right what?" "Right, ma'am." "Excellent. Now, back to where you started." You take up your pencil again, working your way through k-space at Ms. Harshwhinny continues to use you as her personal footstool, her toes idly wriggling against the back of your neck.
