For example, after you get to know the person your comments will be different.

Professional relationships are difficult, especially if you knew the person before.

Q. Did you know the person who came out of the church?

You feel you're never going to get to know the real person.

"Which makes it likely that he knows the person with the machine well."

"He did not know the person well; that was so far away from anything I could do."

"Even if they don't know the person who has died, people here feel like it was their brother."

It didn't matter how long you had known the person.

I know the person we're looking for will be here tonight, and I'll recognize who it is.

Take my word for it, he had to know the person.
