Dr. Caldwell described emotions in the ADHD person’s brain as a very strong dye in the water of the fishbowl. You add some red dye to the bowl, and very quickly the entire bowl turns crimson. Everywhere you look, the water is red, and everything you look at through that water also looks red. But then, if another drop of dye is added to the water, the water instantly switches over to the new color. Now nothing looks red at all anymore. Presto chango.
