Prompt: Petunia awakes one morning to find a parcel on her kitchen table 4 years to the date her estranged nephew came to her lonesome's door.
The words "How To Raise a Respectful Lord/Lady: A Muggleborn perspective" stuck out to her, as a female with greying black hair smiled softly, as she pulled her cloak back over her head, and disapperated.
(TL;DR: Minerva sets Petunia and Harry up for success by letting them know of his inheritence; He grows up knowledge of his responibilities, and 2 loving aunts. Vernon and Dudley dont exist, RW/MW/AD bashing)
