I can barely speak in front of my father. We barely talked during my childhood and he was very strict and "heavy" man. I am adopted and I think he never accepted me entirly, so I was always afraid to talk when he was around, let alone chat with him. I am now 21, still live with my parents, but communication with him is minimal. I also stutter quite a bit when starting conversation with my mom, but then my speach slowly becomes relatively smooth. I also have mental health issues, chronic pain, RLS, tinnitus, list goes on. He never asked me "How are you doing?". Neither did I.
