Hi Paula!

Greetings from London! I am here with my parents and am having a whale of a time. We have been here since Thursday and have already seen and done so much.

On Friday, we went to see The Moscow State Circus. I was so excited as I had never been to the circus before. It was a perfect evening full of amazing tricks. Most of all, I enjoyed watching the trapeze artists flying high up in the air. I have never seen anything like it! It was a hair-raising experience! Luckily, no one fell down! Of course, there were also clowns dressed in funny costumes too, as well as other artists. If you ever get the chance to see this famous circus, you should go – it is an unforgettable experience. And, don’t forget to try the toffee apples – they are the best!

Hope you are having a funny time too. Will tell you more about it when I see you.

Love,

Diane
