On my way to Mammoth Mountain for skiing, I saw a family crossing the street. The children, full of excitement in the heavy snow, took big steps and playfully ran around, while the parents followed behind, ensuring their safety and carrying their snow gear. The scene was full of childlike joy and love, reflecting the warmth and togetherness that often defines family life in the U.S. — where moments like these, simple yet filled with affection, form the heart of happiness in daily life.
