                           My Visit to the Theatre

Two weeks ago my parents and I went to the theatre to watch the opera, Eugene Onegin by Tchaikovsky.

My dad had bought  tickets for us the day before, so we didn't have to queue at the box office. When we arrived at the theatre, we went to the cloackroom to leave our coats there. Then my mum bought a programme to have a look at the cast. Our seats were in the stalls so we had a great view of the stage and didn't need any opera glasses.  

The opera was in three acts, so there were two intervals and the opera lasted about three hours.

At the end I had mixed feelings about the performance. On the one hand I liked the music, the singers' voices and excellent period costumes, but on the other hand I was a bit bored at times.
