and I walk to school together, but we're not in the same class for every subject.
John is very good at sports and he plays for the school football team. He likes
music and he has guitar lessons, but he's not very good at playing the guitar.
John lives opposite my house. He lives in a semi-detached house - all the
houses in the street are semi-detached. John's got a brother and a sister. He
shares a bedroom with his brother.
