My boyfriend gave me a gift.

Everyone was surprised by the news.

When I hear that song, old memories come to mind.

This was truly an unexpected result.

I am surprised by this unexpected event.

His thoughts were as we expected.

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.'

He understands the meaning of the proverb 'Teaching is half learning', which means that teaching leads to one's own learning.
