"Luna
had decorated her bedroom ceiling with five beautifully painted faces:
Harry, Ron, Hermione, Ginny, and Neville. They were not moving as the
portraits at Hogwarts moved, but there was a certain magic about them
all the same; Harry thought they breathed. What appeared to be fine
golden chains wove around the pictures, linking them together, but after
examining them for a minute or so, Harry realized that the chains were
actually one word, repeated a thousand times in golden ink:
friends…friends…friends…friends… Harry felt a great rush of affection
for Luna"
