Are you going to leave school at the end of the term?
Yes, I am.
What are you going to do?
I'm going to be a clerk.
What does a clerk do?
He works in an office. He writes letters and reports, and he types.
I want to be a vet.
A-what?
A vet-a veterinary surgeon.
Good gracious! What's that?
A vet's a man who takes care of sick animals. He's an animal doctor.
I once read a story about a person who talked to animals. It was very interesting.
