Red Pen on the Wall

Someone in London is correcting the graffiti. The Tutor Crowd, a British tutoring platform, has been dispatching people through the city to quietly annotate the spray-painted mistakes they find—apostrophe errors, misspellings, the kind of confident wrongness that normally only appears on walls and school whiteboards. They leave a neat correction and a company sticker. Passive-aggressive tutoring as street art. The vandal came to make a statement; the tutor came to grade it.

The photos are genuinely funny. A tag confidently misspelling something obscene, and right beside it, a careful red-marker fix. The implied message is irresistible: if you’re going to commit a crime, spell it correctly first. Anyone planning a 3 a.m. illegal excursion with borrowed spray cans and questionable companions should probably open a dictionary beforehand—otherwise they’ll come back in the morning to find their work peer-reviewed by a stranger with better grades.

Every English teacher I ever endured would have lost their mind over this project—not over the ethics, but from the sheer frustration of not having thought of it first.
