polygraph greg passed

Greg is one of those sociopaths that can pass a polygraph the problem is the polygraph reader told me that there was some things that Greg said to him that he had never heard in his entire career he had been  conducting polygraph test for more than 20 years . We all know that it's about the polygraph reader  and not necessarily the polygraph machine . So when I went to pay for a polygraph the reader  announced to me that Greg was lying cuz he said some crazy stuff the polygraph tester never heard and his life  so why did he tell me that he passed the polygraph  that doesn't make any sense  it seems to me I wasted $250 .  If somebody ask you if you rape your wife or hurt your wife in the bedroom and you say not on purpose it was an accident  there's something wrong . And that is one of the many things the polygraph reader said that he had never heard and all of his life because you don't accidentally rape somebody
