THANK YOU VERY MUCH!

I had never been so surprised in my whole life. I knew that I could not make it, I can’t sing as good as Emily the second finalist in that competition. Emily was called to sing in front of the judges. She missed couple chords and judges didn’t like him at all she, instantly left from the stage. She was crying and shaking all over her body. I knew that this same thing could happen with me.
Suddenly the called my name Marily. I stood up and I breathtakingly looked towards the door. I walked to the stage. 30 000 people and judges who were gathered to that hall were looking at me. Judges asked me some different questions and then they asked me to start singing. I started singing and judges were admireing me. I added emotions to that song, I laughed when it was needed, I dropped a tear when the song turned to sad. After my song judges stood up and applaused. I were extremely happy I didn’t knew what to do.
After Emilys second song the winner was accounced and it was me! I won 100 000€ and trip to Ireland. I have never been so surprised in my whole life, because Emily was soo much better singer than me. You only need courage and all your dreams come true!
