Didn't Look Like Deep Emotion

He spent 18 years in prison. In that time, i'm sure he built up a lot of anger and frustration. Most people would think if they had come out for having served 18 years for a crime, you'd be feeling pretty angry the point where you've been exonerated. I can see somebody being elated that they finally got out, but having this sort of simmering w they wasted half my life kind of anger built up behind it. But isn't there some people who just don't have that depth of emotion thay literally operate on on one plane, that really think that deeply?
