A gentle wind can cool a summer day, but a strong wind can become a powerful hurricane of terrifying force. This idiom refers to something that floats lightly in the wind like the smell of freshly baked bread. The reference, however, is not to a smell but to a sound. It seems the wind can sometimes cause whispered conversations to carry over long distances and be heard by other ears that have no right to listen.
