I guess he knew a thing or two about romance, but in his own way. As a teenager, Grandma said "even if that man (Grandpa) was the last man on earth, I still wouldn't marry him." A little later, they had to share a 3 hour car ride from the country to the city. I guess he won her over because they were married six weeks later. He managed to keep her for 58 years and kept his promise of "till death do we part".
He wasn't the roses and candies kinda guy, but he did do things that grandma thought were romantic. He would build her quilting frames, do most of the cooking, and kept the garden beautiful and full of foods she liked to eat,bake, or can. Gram loved to sing so gramps learned to play several instruments. He accompanied her for over 50 years. They were so cute as they got older. They would flirt in their own little ways and he would call her "Ms Lucy". Granted, they had their fair share of fights and patches of tough times over the years, like any marriage. But, after all that time, when they looked at each other they still had love and respect in their eyes.
So, go make a "romance sandwich" already!
