ohboywonder:

is that no teacher ever called him James by accident, or that Ron never was called “Bill-, eh Charl-, no Per-, argh!”

As a younger sister who knows this struggle all too well: THIS IS REAL. Pretty sure 70% of my past teachers still think I’m called what my sister is called in fact.

Imagine Fred being called Percy by McGonagall accidentally and then he gets so offended that he refers to her by “Professor [insert any other name but McGonagall” for the rest of the year, costing Gryffindor a considerable amount of points one at a time.

From then on, she vows to just call them all Mr Weasley.

Until Ginny comes along and she calls her Mr Weasley by accident and Ginny “accidentally’ calls her Sir and it starts again.
