There is an old Indian proverb that says no one has the right to criticize another until he has walked a mile in his moccasins.  It's the same principle that Jesus articulated so clearly when he said, "So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets" (Matthew 7:12).   Every major religion in our world has a paraphrase of this as a guide for humankind, yet how seldom do we really stop to consider what difficulties, what pain, what stress others are facing.  Consumed with our problems, our cares and difficulties, we seldom ask, "If I were in his shoes, would I be doing things any differently?"
