"Those are the kind of little things that bond you with someone," he said. "There are friends that you love in a real friend way, not in a, you know what I'm talking about. I love Lon. That's why he was so important to me, that's why he was at my wedding..."

He trusted Monk "infinitely," he adds.

While all this personal history goes on, some jurors react. One looks extremely annoyed by the testimony. Another has her hand on her chin, still engrossed. One is "resting" her eyes.
