Harry Potter and the Order of the Phoenix

5th re-read:

《Though condemned I am to split youStill I worry that it's wrong,Though I must fulfil my dutyAnd must quarter every yearStill I wonder whether SortingMay not bring the end I fear.Oh, know the perils, read the signs,The warning history shows,For our Hogwarts is in dangerFrom external, deadly foesAnd we must unite inside herOr we'll crumble from within.I have told you, I have warned you...Let the Sorting now begin.》
