I am driving home from work in the rain. The traffic is heavy and I am upset. Not at anything in particular, just a strange combination of angry-sad, non-focused malaise. I have a feeling of something wrong, there is something missing. And the rain is coming down and I can’t see and that jackass in the Audi just cut me off. And I don’t know why I feel the way I do. So I grip the wheel tight and concentrate hard on the wet road and squeeze my brow together so tight it hurts my head. I grind my teeth.
