Lomax and I were crossing a very busy Wilshire Boulevard intersection during lunchtime today (we had the "walk" signal) when a guy in a gigantic SUV made a right turn directly in front of us. He was going way too fast, for one thing. He had been looking, and knew exactly what he was doing. Looked right at us and stuck his hand out the window in a kind of wave, a signal of thanks that we were letting him go as well as a signal that he was going whether or not we were letting him.
Judging his distance to be just far enough away, I didn't react physically -- kept face-forward but pretended not to see him, and kept my pace, which was moderate and measured. A split-second of terror flashed across his countenance, which I confess delighted me.
Sometimes people think I'm blind when I'm wearing my black sunglasses, and walking Lomax in his GDA service jacket.
