Our reading
An editorial interpretation.
The effort needed to speak kindly is contrasted with the length of its effect. A brief remark can remain with someone long after the conversation ends. The echo makes that influence feel larger than the original sound, giving ordinary words a lasting importance that their simplicity might conceal.
