Nick: What are you doing, Phong?
Phong: I'm drawing my house.
Nick: Your house! That's a UFO.
Phong: It looks like a UFO but it's my house in the future.
Nick: Where will it be?
Phong: It'll be in the mountains, surrounded by many tall old trees.
Nick: What will it be like?
Phong: It'll be a large house. There will be twenty rooms in it.
Nick: Twenty rooms! Wow! Will it be nice?
Phong: Yes, and it will have solar energy.
Nick: Fantastic! Which room will you like best?
Phong: My bedroom, of course.
Nick: What appliances might you have?
Phong: I might have a wireless TV so I can watch TV programmes from space or a friendly robot to help me with my home.
Nick: Sounds great! And how much will....
