I love to see Cirque du Soleil. They have different themes for shows. One year my daughter gave me a wonderful treat for my birthday. It happened that Circus de Soleil came to town. She bought tickets online. What I was impressed about the show was that there were many farces happening at the same time as the main act. It kept me entertained, and laughing all night.
I think people working in the circus have their brain wired differently!
