She did not say one word.

She gathered her leather folder, and she stood, and she walked out of my house, and the front door closed quietly behind her, and that was the last time she ever crossed my threshold.

She went without a word, and the quiet way she went told me more than any argument could have.

A person who believes they have been wronged protests; they rage, they threaten, they make their case.

Shirley made no case.
