I will never forget my first visit to the theatre. My mother took me to the Bolshoi theatre to see "The Sleeping Beauty". We took the underground there, as the Bolshoi Theatre is in the centre of Moscow. It took us a quarter of an hour to get there. When we arrived at the theatre we could see many people in the hall. Some of them had programmes in their hands . My mother bought one for us. Then she lad the way to our seats. They where not expensive but we could see the stage very well. Then the lights went down and the curtain rose. We could see a beautiful palace on the stage and we could here beautiful music. The scenery was fantastic. I liked the ballet very much. The leading dancer was so good, that when the performance was over there was a storm of applause. My mother enjoyed the performance greatly and she promised to take me to the opera at a later date
