SHMILY
My grandparents were married for over half a century, and played their own special game from the time they had met each other. The goal of their game was to write the word “Shmily” in a surprise place for the other to find. They took turns leaving “Smily” around the house, and as soon as one of them discovered it, it was their turn to hide it once more.

They dragged “Smily” with their fingers through the sugar and flour containers to wait whoever was preparing the next meal. They smeared it in the dew on the windows overlooking the patio where my grandma always fed us warm, homemade pudding with blue food coloring. “Shmily” was written in the steam left on the mirror after a hot shower, where it would reappear bath after bath. At one point, my grandmother even unrolled an entire roll of toilet paper to leave Shmily on the very last sheet.

There was no end to the places “Shmily” would pop up. Little notes with “Shmily” scribbled hurriedly were found on dashboards and car seats, or taped to steering wheels. The notes were stuffed inside shoes and left under pillows. “Shmily” was written in the dust upon the mantel and traced in the ashes of the fireplace. This mysterious word was as much a part of my grandparents’ house as the furniture.

It took me a long time before I was able to fully appreciate my grandparents’ game. Skepticism has kept me from believing in true love- one that is pure and enduring. However, I never doubted my grandparents’ relationship. They had love down pat. It was more than their flirtatious little games; it was way of life. Their relationship was based on a devotion and passionate affection which not everyone is lucky enough to experience.

Grandma and grandpa held hands ever chance they could. They stole kisses as they bumped into each other in their tiny kitchen. They finished each other’s sentences and shared the daily crossword puzzle and word jumble. My grandma whispered to me about how cute my grandpa was, how handsome an old man he had grown to be. She claimed that she really knew “how to pick ‘em”. Before every meal they bowed heads and gave thanks, marveling at their blessing: a wonderful family, good fortune, and each other.

But there was a dark cloud in my grandparents’ life: my grandmother had breast cancer. The disease had first appeared ten years earlier. As always, Grandpa was with her every step of the way. He comforted her in their yellow room, painted that color so she could always be surrounded by sunshine, even when she was too sick to go outside.

Now the cancer was once again attacking her body. With the help of a cane and my grandfather’s steady hand, they still went to church every morning. But my grandmother grew steadily weaker until, finally, she could not leave the house anymore. For a while, Grandpa would go to church alone, praying to God to watch over his wife. Then one day, what we all dreaded finally happened. Grandma was gone. “Shmily. It was scrawled in yellow on the pink ribbons of my grandmother’s funeral bouquet. As the crowd thinned and the last mourners turned to leave, my aunts, uncles, cousins, and other family members came forward and gathered around Grandma one last time. Grandpa stepped up to my grandmother’s casket and, taking a shaky breath, he began to sing to her. Though his tears and grief, the song came, a deep and throaty lullaby.

Shaking with my own sorrow, I will never forget that moment. For I knew then that, although I couldn’t begin to fathom the depth of their love, I had been privileged to witness its unmatched beauty. S-H-M-I-L-Y: See How Much I Love You

Thank you , Grandpa and Grandma, for letting me see.
