A last name that belongs to someone who thinks they’re the king of the world and you’re just a peasant.

My cousin’s friend is Nagasawa and he thinks he’s the king of the school.

My neighbor is Nagasawa and he won’t stop talking about how he’s rich.

I asked him for help and he said, 'I’m Nagasawa. I don’t help peasants.'
