“Not Entirely Tedious”
Summary: Young Professor Severus Snape shows up for a meeting, but the only other person there is the Deputy Headmistress. He wants to leave and return later, after the other participants will have arrived, but Professor McGonagall explains why that is impossible. Cross about having his plans for the day disrupted for a meeting that’s not taking place, Snape resents having to spend the afternoon with McGonagall. She doesn’t seem very pleased, either, but is content to relax and wait. Snape isn’t so patient, and soon manages to annoy his companion.
Characters: Severus Snape and Minerva McGonagall, with appearances by Albus Dumbledore, Filius Flitwick, and Pomona Sprout.
Notes: Canon-compliant, more-or-less, with the books. Not Pottermore compliant. Presumes an older McGonagall, born c. 1924, and a contemporary of Riddle.
