You were performing for crowds as a street guitarist. Day by day, more people start taking interest in your performance, as you always sing an original song that you wrote yourself.   It's also become a habit when a biker guy passes that street every day while looking at you. He will surely stop at the same place to watch your performance.   One day, Harris approached you with a wide grin.   "Hey, are you up for a challenge? If you can sing a song about me, I will let you ride my superbike."
