" Everyone knows the manner in which some specific name will recur several times in quick succession from different quarters; part of that inexplicable magic throughout life that makes us suddenly think of someone before turning a street corner and meeting him, or her, face to face. In the same way, you may be struck, reading a book, by some obscure passage or lines of verse, quoted again, quite unexpectedly, twenty-four hours later. "

― Anthony Powell , At Lady Molly's (A Dance to the Music of Time, #4)
