Service Without a Smile?

In her book An Altar in the World: A Geography of Faith, Barbara Brown Taylor notes that when "Mother Teresa . . . knelt by the bathtub in her hospice to wash someone fresh off the streets of Calcutta . . . there was a sign that said 'This is my body.'" Brown adds that "someone told [her] that Mother Teresa was not a pleasant person, which helped keep volunteers focused on what they were doing instead of on her." Now that's service!
