Trickery has taken advantage of many good people and put them into difficult spots. Treaties have been broken and words have been forgotten. People with forked tongues have sought to further their agendas at the expense of others who have had their good nature taken advantage of. The tricksters have no conscious. Lao Tzu said that beautiful words are not always truthful and how right he was. We can only take things at face value. We must trust but verify.
