Friends are your friends because they like you. In the same respect someone you might see on TV and not like, such as a defense attorney for example, you could meet at a cocktail party and really enjoy a conversation with them and think this person is really not what I thought.
Interactions between friends is far more intimate and accurate than just an impression of a person we read about. TA seemed to be like by both his friends and his associates alike. To most of us he seemed likeable. Since he was so successful in bringing people into the business with his motivational speeches I would think there were many who liked him and were inspired by him. It was not just an act, it was who he was and you can see it by what he wrote in his blog.
JA, however, was disliked by her associates at work and had very few friends. What does it tell you when one of the few witnesses she is calling for her defense was in maximum security with her???? No friends other than a cellmate and an old boyfriend. jmo
