I didn't know at first why he'd brought the subject up.

Then why bring up the subject so early, some people ask.

It was her mother who brought up the subject of their return home.

After all, they brought up the subject in the car.

I shouldn't have brought the subject up in the first place.

He still knew better than to try to change his wife's mind about anything, however, and hadn't even brought up the subject.

At least, that's what he told me the one time I brought the subject up.

After a moment the man went on as if he had never brought up the subject.

The man who had brought up the subject said no more.
