"Not in sentimental or grand gestures, but gentle ones, a moment of listening, a word of comfort, a friendly conversation, a helping hand. Presence. These simple acts of care might seem small, but they contribute to the beautiful tapestry of life to which we all belong."
Princess Kate's talent for playing the piano was revealed in 2021 during her first "Together at Christmas" carol service. Then, she accompanied Tom Walker on the keys in her first public performance for a rendition of his song "For Those Who Can't Be Here."
