Not wanting his skills to waste away in his twilight years, he passed down everything he knew to his son. His son developed a love for music. He was eager to please, so he quickly picked up on what he was taught. With Talent and determination, he learned to excel in any instrument. If it has strings, then he can play it. Music is his joy in life and performing gives him meaning. Having always been popular since he was young, he loves to be the center of attention.
