Number Three
Growing marijuana or hallucinogenic mushrooms is not 'an extra credit project for Herbology.'
"How… many times have you been sent to my office this year, Mr and Mr Weasley?" Professor McGonagall asked, somewhat wearily, staring over at the two boys as Fred grinned and George, attempting to keep a straight face, counted on his fingers, soon running out of fingers.
"Erm… quite a few times, Professor."
"And how many weeks into the year is it, Mr and Mr Weasley?"
"Erm…"
"Two weeks, Mr Weasley. Two. Weeks." She snapped, rubbing at her forehead and giving a quiet sigh. "What have you done this time?" She asked, a moment or so later, reaching forward to take hold of the note that had been sent with the two troublemakers.
"…"
There was silence for a few minutes as she read, then re-read the note, before simply letting it drop from her grip, the slightly curled paper floating gently to her desk.
"I will, of course, be writing to your mother about this… and as your punishment, I think… I think that lines shall have to suffice… seeing as whatever punishment I put upon you, you'll just end up breaking some other rule…" She murmured, her voice now slightly muffled due to the fact that she had placed her forehead down upon the surface of the desk, her eyes closed, her hat tilting forwards a little but somehow managing to stay on her head.
"What do we have to write, Professor?" Fred asked, his voice gleeful. Lines were an easy punishment, besides, with a simple spell, they were written out extremely quickly.
Professor McGonagall sighed as she sat upright once more, her forehead a little red from where it had pressed against the desk, and she unfurled a scroll of parchment, dipping her quill into ink and beginning to write. She waited a few moments for it to dry, before curling it up once more and handing it over to George, gesturing weakly for the two of them to leave. No doubt she'd be seeing them again within the next day or so.
The twins toddled quite happily out of the door, closing it behind them and immediately unfurling the parchment, laughing slightly.
"Growing marijuana or hallucinogenic mushrooms is not 'an extra credit project for Herbology.'" George read, laughing again as he and his brother began the walk back to the Gryffindor common rooms.
