My opinion is that this guy is extremely intelligent, anylytical and logical. He is talking so much because, as someone else said, he is talking out his thoughts while he figures it out. My husband is an engineer and he is very, very logical and puts a lot of thought into his words. There is no way they would ever want my husband on a jury. He is also the type that questions everything. For instance, that question JB asked about can you prove a negative, well, yeah, my husband will not only tell you that you can (if it is at all possible), but will go into a lengthy discussion about why and how to do it. LOL I love him very much, but there is no such thing as a "simple conversation" with him. In his job, he has to be this way, as he is a trouble shooter, problem solver, brain stormer, etc. He is excellent at his job but this always spills over into daily life. JB would never be able to keep up with him when being questioned if my hubby had to do this. I think this guy is the same type of person. He is trying really hard to give short answers but just cannot do it.
