Here's what submitter Victoria told me about this card, which is probably some kind of code about the occult or something:
I received a sympathy card in the mail at my work place, and the
photo below is the contents of the card. The front of the card simply
said "Sympathy" on it in gold script and the envelope's return address
was a local public library. We've been speculating for a couple of
weeks now as to the meaning of the card, but whomever sent it is a huge,
huge fan of using quotation marks in inappropriate ways. This card is
like a user's manual on different circumstances in which not to use
quotes, and the mysterious message makes it all the more compelling.
