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 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 said, 'Where there is a will, there is a way,' and faced the difficult situation.

He strongly believes in the philosophical thought, 'I think, therefore I am.'

He chose a stable job, saying 'a bird in the hand is worth two in the bush.'

He always keeps in mind the phrase 'If one learns without thinking, it is a waste.'
