This is the correct response. Hopefully it heard you through all the fat lining its ear canals and felt the shame deep within its fatty core. But remember: It's not fat-shaming on your part. Shame comes from within. If it felt shame from your pointing out its disgusting condition, it's because the creature already knew it was in the wrong. Shame is a GOOD thing. Shame tells you "maybe I should NOT do this." Unfortunately, the shame felt by sofa bisons is always outweighed by their desire to ingest more grease.
