Well, let's introduce ourselves. My name is Christian, I'm an English teacher from La Serena. I work in Elena Bettini school. I'm married and I have three daughters, they are all students. I like reading, playing music and watching movies.
What about you?

La Serena is a very beautiful city, full of nice places to visit and enjoy. Some people like nature, others enjoy more crowded places. My favorite one is the beach, you can enjoy a nice evening walking along it, rest in the sand, swim or have something to drink or eat. What's your favorite? Why?
