He is ninja, you can't see him
James has expressed a desire to follow a career path that includes motorcycles, saving kitties, and being a ninja. If he can pull off the trifecta, good for him.
So far, he's honing his ninja skills quite well. The boy has developed an ability to hide in your blind spot. So you'll be walking through the mall or in a store, and James will suddenly disappear from view. Then you'll swivel your head around, and there will be no sign of him, as he's nowhere in your peripheral vision.
Then, in a panic, you turn your whole body around -- and find him standing there, not a foot from you.
Staring at you.
Close enough to kill you with his bare hands, if he had ninjitsu training.
Of this I am sure.
