Prince: Hello Professor Parrot.

Parrot: Hello Prince Ahmed.

Prince: What are you doing?

Parrot: I'm trying to figure out how big the Earth is.

Prince: That's hard for me but it's less hard for you.

Parrot: Really but, but HOW?!

Prince: Just think about it. I'm a human and you're a bird.

Parrot: Yes, I am a bird but what does that have to do with the question?

Prince: You can explore and fly and I can't.

Parrot: Yes, I can explore the world by flying.

Prince: Yes, you can.

Parrot: I will take your suggestion and start my journey now.

Prince: Bye, Professor Parrot.

Parrot: Bye, see you another day.

Prince: And when we meet you have to tell me how big the Earth is.
