My grandma would always x out people in her yearbook and write “Deceased” when one of her high school classmates died. We often found it morbid. Grandma wanted to be the last one living. She wanted to win.
That’s not a yearbook.
That’s a hit list.
a muggleborn student gets called a mudblood, so they lick their hand and wipe it on the pureblood’s face, singing “got mud on your face, you big disgrace, somebody better put you back into your place”
