This has happened to me, though never with a Kodiak brown bear. But it has with possum, raccoon, fox, and various birds. The critter in question is suddenly at your side, as a 'normal' compadre. How does this happen? I submit that energetically, you have become one with the surroundings, and the critter therefore does not feel threatened. It's an interesting process.

This fellow seems tired, as evident when he sat down. It's an act of trust to exhibit weariness. But I suppose one can wonder if he wasn't in his right mind at the time of this event. Perhaps his unconcern was a function of illness. He did look momentarily like he was going to hang out with the photographer for a while.
