He always keeps a smile on his face.

He often quotes proverbs in his conversation.

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

His red shirt stands out in the crowd.

This dress fits me perfectly.

He said, 'This problem cannot be solved.'

I couldn't understand his actions.

He started to act immediately.

He always acts conspicuously, which reminds me of the proverb, 'The nail that sticks out gets hammered down.'

He nailed a nail into the wood.
