My In-laws celebrated their 69th wedding aniversary in February this year. They've had their ups and downs over the years, as well as "in sickness or health. We're blessed to have them here still. I remember a few years ago my father-in-law did not speak to my mother-in-law for nearly 3 months. He didn't want to interrupt her.!
Congratulations on 64 years. All the Best.
