Actually in real life, I have been working on filtering myself. My mouth often gets me into situations those around me would really rather not face. People often think being unfiltered means they cuss like a two year old that just learned a new word. That is childish, not unfiltered.
Long Term Care facilities are full of people with dementia who also love speaking their mind with no filters. Why would you want to equate your demeanor with someone who's nearing the end of their life cycle who simply don't know any better than to speak their mind with no filters? Truth is, they can't help their mentally degenerative disease. What would be your excuse if you don't already suffer from dementia?
