Answer to Trivia Question:

Harry Potter and the Deathly Hallows begins with the following William Penn quotation:

“Death is but crossing the world, as friends do the seas; they live in one another still. For they must needs be present, that love and live in that which is omnipresent. In this divine glass, they see face to face; and their converse is free, as well as pure. This is the comfort of friends, that though they may be said to die, yet their friendship and society are, in the best sense, ever present, because immortal."

from More Fruits of Solitude, 1702.
