She always stutters and spammers. She can’t remember the last lie she told. When you lie you talk like she does because you have brain cramps trying to remember what you said in the past. When you tell the truth the words come out easier.
Remember Kraft Mystery Theater? Circa 1960. I remember one where some kid was being groomed as a prince and heir apparent to the throne of some fictional Asian country. Some guy who remembered him as an infant had a test question, what was his pet toy? When challenged the would-be heir became flustered and nervous, blurting out, "they told me what to say, but I forget it." Of course, that was it and the party was breaking up, and the kid goes into truth mode and dreamily remarks, "I never wanted any of this. I just wanted to be a sailor. I had a little sailboat that I loved." The challenge guy is just leaving and hears him. "That was it!" he exclaims. So there you are.
