They say that laughter is the best medicine. Does it always work? There are times when I just don't feel like putting on a happy face when I feel bad inside. They told me that I have a very expressive face, meaning that I don't succeed very well in hiding my feelings. But on the whole, I have a smiley face. I just don't feel that way tonight. St. Therese said there is such a thing as "holy hypocrisy."
