 Hemming complained that Oswald boasted too much about his inside knowledge.For instance, upon their first meeting; Oswald tried to impress Hemming by showing off how much he knew about Hemming's background and mission - somebody in an intelligence capacity had briefed Lee Harvey Oswald, and Oswald sort of teased Hemming with this information.So, Hemming did not particularly enjoy the company of Oswald from the start.
