Joe, a Concert Pianist, Was Walking Down the Street When

Joe, a concert pianist, was walking down the street when he was struck by Harry, a careless skate boarder. Joe was knocked down and crushed his hand. When Joe sued Harry for his negligence, claiming the loss of income from his profession (he could never play the piano again), Harry countered with the defence that there was no way he could have anticipated that the person he was going to hit was a concert pianist. Explain his likelihood of success in raising this defence.
