"He returned to the common room half an hour later to find Hermione and Ron in the best seats by the fire; nearly everybody else had gone to bed. Hermione was writing a very long letter; she had already filled half a roll of parchment, which was dangling from the edge of the table. Ron was lying on the hearthrug, trying to finish his Transfiguration homework.
“What kept you?” he asked, as Harry sank into the armchair next to Hermione’s."
-Harry Potter and the Order of the Phoenix, Chapter 21
