     Our school had a series of activity for Girls' Day. I had
great difficulty decided to take part in the singing competition with my
roommates. It was a really challenge for me because I had never sung 
on the stage. We choose the song Seasons in the Sun and changed
the words.

To make sure our performance was good, they made great efforts to
practise it again and again. Therefore, when time came to
perform, I  
               
was too nervous to remember any words of a song!
Although result was that we failed to make the finals,for me, 
Having courage to sing on public was a great experience. I believe the
Chance I grasped it has been a turning point in my life.
