If it is, indeed, a virtue at all?
Our American culture tends to value a kind of superficial friendliness. Our Protestant neighbors often excel in offering a friendly demeanor and a smiling countenance.
But it is reasonable to expect someone, for example, who is suffering severe pain, to always be warm and friendly. Should a person who tragically lost wife and children in a disaster attend the funeral with smiles and cheerful quips for everyone?
I think not. Instead, there will be tears, shortness of words, and a focus on the most serious aspects of life.
What do you think?
