Kathy and Brandon were reminiscing about their marriage nearly 9 years ago while they were talking about an upcoming wedding in Kalamazoo, Mich. they are attending.
They were wondering what to get the couple-to-be, and were talking about the wedding gifts they received on their special day.
It was a gift from Kathy's Great Aunt Alison. It was a simple white box with explicit instructions to not open until their first 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," Karen wrote in a Facebook post.
Kathy says the box survived 9 years and three moves, and always just sat high on a shelf in various closets collecting dust.
Kathy assumed the key to saving a marriage was in that box. It had to be, after all, since Aunt Alison and her husband had been married for nearly 50 years.
But, on this night, Kathy and Brandon decided to open the box.
"That box went beyond what I believe my Great Aunt had intended. It was by far the greatest wedding gift of all," Kathy writes.
So, what was inside?
Two separate notes addressed to Kathy and Brandon, wrapped around cash.
Brandon was instructed to use the money to buy flowers and a bottle of wine.
Kathy was told to "get a pizza, shrimp or something you both like" and to get a bath ready.
