Last autumn my cousin invited me to the Bolshoi Theatre to see " Swan Lake", the famous ballet by P.I.Tchaikovsky . When we arrived at the theatre , we left our coats at the cloak room and went to the stalls where our places were. Soon the lights went down , then the curtains rose and the dancers appeared on the stage . I liked every minute of the first act - the scenery , the costumes , the music and the way they danced . When at last the ballet was over and the music came to an end , there was a storm of applause. I told Alec how much I liked the ballet . I said I would love to see some other ballet some day . So we went to the box office and bought two tickets for " The Nut-cracker .
