My husband remembered our song for one verse

Dear Delyara, My husband has dementia and often does not know who I am. Today, at the care home, someone played the song from our wedding. He was staring out the window when the first notes began. Then he turned toward me and sang the opening verse perfectly. His voice was weak but the words were all there. He took my hand in the exact place he used to take it when we danced in our kitchen. For less than a minute, his face looked familiar from the inside. At the chorus, he stopped and asked my name. The moment ended. I told him, and he nodded politely. I used to believe a good day required sustained recognition, conversation, and proof that our shared life remained intact. Today, one verse was enough. Memory opened briefly, let me stand inside our marriage again, and closed. I went home grieving, grateful, and still humming.
