Hi...my dad is 77 and my mom is 67. My dad is using more profanity to my mom now more then ever. For example, the other day my mom would bring home food...but it wasn't to his satisfaction. So he's start cursing and calling her any negative word/name he can think of. This is obviously depressing my mom and myself. What mechanisms can I do to combat this issue with my dad and bring peace back to my home and family?
