My dear high school sweetheart and wife of 34 years has saved every card and letter the two of us have ever given to each other. I can recall this collection growing yearly, until it grew to a size far larger than its original shoe box. Some years ago I found and gave to her as a gift a painted wooden chest; she immediately turned this into her “treasure” chest, and since has stored our cards in it.  Our cards to each other are impassioned, at times explicit and always quite expressive of our love for each other; you could say its for “our eyes only”.  My contribution to this chest is inspiration for this write a few years back.
