Jack couldn\'t play the guitar until he was fourteen years old. This was because he didn’t have time. He had to help his father in the family shop every day. He didn\'t have to work on Saturdays, but there was still no time for music. When he was fourteen, his father sold the shop and his son could have the guitar lessons he’d always dreamed of.
