Just one uncaring word can spark a fight.

Just one cruel word can shatter a life.

Just one harsh word can sow misunderstanding.

Just one disrespectful word can douse the fervor of love.

Just one kind word can smooth a rocky path.

Just one joyful word can cheer a gloomy day.

Just the right word can lighten an uneasy heart.

Just one affectionate word can show the beauty of the world.

(a centuries old Korean poem, author unknown)
