Did you know?

A placid lake has a smooth surface untouched by wind. A placid scene is one in which everything seems calm; it may even include a meadow with a few placid cows grazing on it. Someone with a placid personality has an inner peacefulness that isn't easily disturbed. As a personality trait, placidity is surely a lot better than some of the alternatives; however, the word sometimes describes people who are also a bit passive, like those contented cows.
