-- Harry Potter (HBP4)
"I think the word 'fiasco' would be a good one here."

July 13, 1996 – Harry and Dumbledore travel via Side-Along Apparition to the Burrow, arriving just after midnight. Before going in, Dumbledore takes Harry aside. In an uncharacteristically intimate conversation, the two discuss Sirius’ death and Harry’s reaction to it, the fact that Harry should confide in Ron and Hermione, and that Dumbledore wishes for Harry to have private lessons with him during the upcoming school year.
Dumbledore and Harry travel to Budleigh Babberton to recruit Horace Slughorn very late on July 12. They arrive at the Burrow just after midnight on July 13.
