Speer stated that Hitler often spoke at length about his favorite subjects while dinner guests were reduced to silent listeners. In the presence of his "superiors by birth and education" Hitler made a sincere effort to "present his thoughts in as impressive manner as possible".

Complete transcripts would reinforce the sense of stifling boredom".
