Our company is a subsidiary of a major corporation.

He works at a major public company.

It's better for him not to know the truth. After all, ignorance is bliss.

He is feigning ignorance about that problem.

He knows that pain through his own experience.

I have no way of knowing what he is thinking.

He is working hard to make his abilities known to the world.

In order to understand his feelings, I had a deep conversation with him.

God only knows what he is thinking.

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