Dear Pete,
Greetings from Rio de Janeiro! It's a beautiful place but it's much noisier and more crowded than London.
There's so much to see and do here. Rio has the most famous carnival parade in the world and trust me it is fantastic! It also has one of the biggest football stadiums in the world, Maracana. You can't believe the size of it! It can seat 150,000 people. Right now I'm relaxing on the beach. Are you jealous?
Dave
