This is what Nadav's mother wrote on her Facebook page:
Last Friday, we called a pest controller named Yossi Moyal to our home. During a conversation with my children, Yossi caught onto my 19-year-old autistic son, Nadav. Nadav shared that his greatest love is singing and music in general. Yossi stepped out of the house for a few minutes, made a phone call, and five minutes later his son, Harel Moyal, walked in.
We met a humble man who came unannounced to honor his father's request, without cameras or documentation, purely to bring happiness to this amazing child. He sat on our couch, tuned my old guitar that had remained silent for 19 years (since Nadav's birth, I hadn't managed to play a note), sang to the astonished children, and even invited Nadav to join him in a song.
Allow me to thank you, Yossi and Harel, for creating such a rare personal moment with your kindness. You moved us with your humility, mutual respect, and admiration, and gifted us an unforgettable experience.
As the door closed behind them and a stunned silence fell over the house, Nadav whispered to me, "You see, mom, sometimes dreams do come true".
