As I look at my weekend ahead, and the one behind, my family has 3 significant wedding anniversaries being celebrated. Brace yourself - 29 years, 50 years and wait for it.... 68 years. Incredible!! Those couples entered into a contract all those years ago and clearly had an evergreen clause to keep renewing year after year. I know it was not without work and making adjustments as needed. Quite similar to what is required with suppliers that you would work with as a procurement professional.
