Jodi has done these verbal gymnastics all her life and they are maddening to anyone she is sparring (talking) with. She refuses to answer simple questions. She leaves herself wide latitude in her answers. She forces definitions of the simplest words.
People like this use this and many other tricks you will see here to not have to come out and say that they lied.
Jodi knows Juan is trying to impeach her testimony. In direct, she often gave long-winded answers with minute details and, in some cases, the exact time. Now, she is picking all the verbal nits that she can.
Juan is doing a masterful job.
This, from a high-school teacher who taught many people just like Jodi. Oh, and a few parents will do this also.
I believe Jodi also is intelligent...has verbal strengths that should not be underestimated.
