I love music more than anything else. For my opinion, music      
is not just a group of sound. Music calms us down and             
helps us think deep. I can't imagine what the world would be    
like it without music. As time goes by, most of the things       
change, so my feeling for music is always the same. When I      
feel sad or disappointed, it is music cheers me up. When I feel  
all hope is gone, I turn around and find that music was there,    
just like the old friend. For me, the past may be black and    
white, but the future would always be colorful. Even though     
there is nothing leaving to me, I still have my music.
