Being the New Student

The boy laughs and tells you that you're silly. They walk to their desks. You wait for you teacher to tell you where you sit.
The next moment, the teacher walks from his desk and comes to greet you. He says, "Hello! I am Mr. Martinez. It is great to have you here. The kids were so excited last week when they heard they were getting a new friend. Please, walk with me while I show you around the classroom."

What do you do?
