Emotion is funny, how it works. Sometimes We get a Zing from Scent, and sometimes, if a Rhinos are upset or distracted, Emotion affects our processes. We get a skewed idea of what a given Scent means. Or the given Scent gets flattened, losing its redolence and nuance.
The Moral of all that is; We can’t trust our noses if We are flipping out. To a lesser extent, Vision can also be limited, ditto our Hearing. Emotion works as a distraction. We become less discerning.
And that is not a Help because Rhinos live in the Wild.
