‘Praise, flattery, exaggerated manners and fine, high-sounding words were not part of Lakota politeness. Excessive manners were put down as insincere, and the constant talker was considered rude and thoughtless. Conversation was never begun at once, not in a hurried manner. No one was quick with a question, no matter how important, and no one was pressed for an answer. A pause giving time for thought was the truly courteous way of beginning and conducting a conversation. Silence was meaningful with the Lakota, and his granting a space of silence to the speech-maker and his own moment of silence before talking was done in the practice of true politeness and regard for the rule that, “thought comes before speech.” ‘
