AITA for asking why my responsible brother wasn't named as our dad's caregiver?

For years, my parents called my brother "the responsible one" while treating me like the family's emergency button. Then a hospital coordinator told me I had been listed as Dad's full-time caregiver. I asked Mom, "Why isn't your responsible son signing this?" The silence told me I had finally uncovered the lie. ---------------🦦Otter Stories🦦--------------- #reddit #stories #redditstories
