KALAMAZOO, Mich., Sept. 7 (UPI) -- A former Michigan couple who received a wedding gift that instructed them not to open it until their "first disagreement" said they finally opened it 9 years later. 
 
 Kathy Gunn said in a post on the Love What Matters Facebook group that she and her husband, Brandon, received a gift at their Kalamazoo, Mich., wedding from Kathy's Great Aunt Alison. 
 
 "On the plain white box was a card that read, 'Do not open until your 1st disagreement.' Now, there had obviously been plenty of disagreements, arguments and slammed doors throughout our 9 years. There were even a couple of instances where we both considered giving up... but we never opened the box," Gunn wrote. 
 
 Gunn said she and her husband put off opening the box despite their fights because they feared they might one day have a worse "disagreement" and be more in need of the mystery package's contents. 
 
 "All along, we assumed that the contents of that box held the key to saving a marriage -- an age old trick -- unbeknownst to us rookies. After all, my Great Aunt and Uncle had been married for nearly half a century. So, we thought the box would save 'us' -- and in a way it did. That box went beyond what I believe my Great Aunt had intended. It was by far the greatest wedding gift of all. For 9 years (and three moves) that box sat high on a shelf in various closets gathering dust, yet it somehow taught us about tolerance, understanding, compromise and patience. Our marriage strengthened as we became best friends, partners, and teammates. Today, we decided to open that box, because I finally had a realization. I realized that the tools for creating and maintaining a strong, healthy marriage were never within that box -- they were within us." 
 
 The box turned out to contain wine glasses and personal notes for Brandon and Kathy. Brandon's note included cash and instructed him to purchase flowers and bottle of wine, while Kathy's also contained cash and told her to buy "a pizza, shrimp or something you both like." She was also instructed to "get a 'bath' ready." ||||| “Tonight, we tucked our kids in bed and my husband and I enjoyed a glass of wine on the deck. We were talking about how excited we were to attend an upcoming wedding in Kalamazoo (where we met and went to college) and discussing what would be the perfect gift for the newlyweds. So, I thought back to our wedding day (nearly 9 years ago) and tried to recall the gifts that had meant the most to me. The funny thing? The gift that meant the very most was still sitting in a closet… unopened. 
 
 
 
 On our wedding day, my husband Brandon and I received a gift from my Great Aunt Alison. On the plain white box was a card that read, “Do not open until your 1st disagreement.” Now, there had obviously been plenty of disagreements, arguments and slammed doors throughout our 9 years. There were even a couple of instances where we both considered giving up… but we never opened the box. 
 
 
 
 I honestly think that we both avoided turning to the box, because it would have symbolized our failure. To us, it would have meant that we didn’t have what it takes to make our marriage work – and we’re both too stubborn and determined for that. So, it forced us to reassess situations. Was it really time to open the box? What if this isn’t our worst fight? What if there’s a worse one ahead of us and we don’t have our box?!? As my Great Uncle Bill would say, ‘Nothing is ever so bad that it couldn’t get worse.’

– The best wedding present Kathy and Brandon Gunn received at their Michigan wedding was one they never opened—at least not for nine years. That was because the gift from great-aunt Alison came with a special instruction: "On the plain white box was a card that read, 'Do not open until your 1st disagreement,'" Kathy Gunn wrote in a post on the Love What Matters Facebook page, spotted by UPI. “Now, there had obviously been plenty of disagreements, arguments, and slammed doors throughout our 9 years," writes Gunn. "There were even a couple of instances where we both considered giving up ... but we never opened the box." Doing that, she says, "would have symbolized our failure." So the box sat on shelves in various closets through the years, gathering dust. "It somehow taught us about tolerance, understanding, compromise, and patience," writes Gunn in a post that so far has racked up 14,000 likes. Finally, on Aug. 30, after the couple put their kids to bed and had some wine, they decided to crack open the box. Inside, they found wineglasses, envelopes of money, and some advice. To Kathy: Pick up a pizza or "something you both like," and get a bath ready. To Brandon: Go get flowers and a bottle of wine. "It was by far the greatest wedding gift of all," says Kathy. The Huffington Post rounds up photos of the couple here. (A math quiz was enough to tank this couple's marriage.)
