“The states of being on the grungy list are not always grungies. They have their natural place in healthy human emotional life. For example, suppose someone dear to you passed away, and the next day you felt no sadness or grief. That would be unnatural. Sadness in this case would not be a grungy. Now, imagine that ten years after this person passed away, you are still so grief-stricken that you cannot function, hardly able to rise from bed each morning. That sadness would likely be a grungy, with corresponding payoffs. A grungy is an unpleasant way of being that we do not rectify. We might complain, gripe and grumble about it, but we hold onto it.”
