How come my shoggoth mom is letting sis treat me like her master? Mom says it’s good practice but sis is really going overboard with the practice and even tries to watch me sleep until I order her to her room, I also noticed my comforters would sometimes squirm at the edges or glowing yellow orbs appear in the darkness, I thought it was mom but she said she stopped doing stuff like that once I got to “that” age. How do I confront my sis about this?
