Greetings from Venice. It's Carnival time here and we are having a great time. Italians are celebrating Carnival every year in late February. The festival is lasting 10 days and it is being lots of fun. People are wearing lovely costumes, dancing in the streets and going to parties.

It's chilly today. Right now it is raining. Cathy and I are siting in a café. We are waiting for the big parade to begin. A girl just behind us is singing and her friend is playing the violin. Her voice is being great. Have to go now. See you soon!
