He is proud of his national flag.

He participated in the parade while waving the Taegeukgi.

He sent a message to the ship using a signal flag.

He had the Rising Sun Flag hanging on the wall of his room.

He came running while waving the Z flag.

The ship entered the port flying a quarantine flag.

He starts talking about himself at every opportunity, causing trouble for the people around him.

He likes to take a walk in the park at dusk.

He is the type of person who thinks it's a moonlit night if it's bright, so he only has a one-sided perspective.

He thought deeply and said, 'I think, therefore I am.'
