“What is ‘navy’?”
“It’s a group of fighting men. They sail on boats on the sea, defending the city and the lands surrounding it.”
“And ‘city’?”
“Well, a city is like a town, only much, much bigger. Thousands of people live there. They have tall buildings, two and three storeys high, and monuments and fountains. The streets are always full of people, and full of sounds and smells.”
“It’s hard to imagine so many people and all those buildings. Where I come from, there are no more than eighteen houses, built in the trees. We climb great ladders to get to them, and at night, we pull the ladders up so we are safe when we sleep.”
“Only eighteen?”
“Yes. You sound surprised.”
“It’s just that eighteen isn’t very many, that’s all. I thought your village would be larger.”
