Lois Griffin

"Not only are you not the perfect mother, you're the farthest thing from! From the moment you gave birth to me, I had to trust you. I had no choice. I needed you to protect me from the world to, to be my guide, to help me navigate the difficult, confusing, and vulnerable journey to becoming a person. You have done NONE of those things! You're my mother and you took a child's trust and smashed it into bits in a seventeen-year long mission to destroy something that you killed a long time ago! And honestly, when I turn eighteen, I...I don't know that I ever want to see you again!"
