At the end of a fairly harrowing new route, my trainer catches up with us and walks alongside. When you do that, he's following you, not leading. You might have been shielding him from cars coming at you from the right. Tobias wouldn't have had a clue that a car was coming at you. If you're not sure about a crossing, get help or go out of your way to cross where you feel safe.
Most serious accidents happen nearest home when a dog's only goal is to be safely back there.
I've been home now for a couple of months and we are doing very well. Tobias has adopted Vermont, his final adjustment to place, his place. Even though there are people in the world who avoid a blind person like the plague, I have been told that most do smile at Tobias and me. I am quite touchy about how I am seen. In my case, blindness has contributed to my shyness and isolation, a timidity of unnecessary contact.
