Straight out of the Addams Family home library?  The inscription to this book on superstition hopes to "form a smile upon your face(s)."  Can't you picture Morticia knitting a two-headed winter cap for the recipient?  Also, the inscription desires that the recipient will "stay imbedded in the mirror(s) of your mind(s)."  That's surely a curse for the reader to be trapped in an inner hall of mirrors!  (Psychological halls of mirrors are even more difficult to be rescued from than the halls of mirros that wizards use to traverse long distances quickly.  Contrary to popular belief, wizards' halls of mirrors are not used to ensnare their rivals.)  The inscription ends, "When you cry, I taste salt."  That part we agree with: may your enemies' weeping season your every meal.

From Knock on Wood by Carole Potter.
