Is the story about emotional manipulation related to the letters and signs mentioned in the podcast?
I realized that my dad was just nice to me while trying to get something from me. But as soon as he noticed that I wasn't going to open the door or that his emotional manipulation didn't work, he started calling me the worst things he could think of and became extremely aggressive. I think this was his true face. Was it just him being hurt, or was it something else? I don't think so.
