I noticed a man, 35 or 40 years of age, in a dark blue coat, following us.

For some reason, I noticed a couple, a man and woman in their mid-20s.

Hope noticed even a third man sleeping and asked his identity.

Margaret was almost finished when she noticed a man watching her.

This was exactly the kind of woman who had no business noticing a man like him.

You have not noticed such a man as this, for example.

I noticed a young man come out of this house.

He was, David had noticed, a man of amazingly few words.

Then she noticed a man who stood head and shoulders above the others.

He noticed a man and a woman standing by the desk.
