The power of denial is extreme. I have a family member who is 7 inches shorter than me and literally weighs double what I do. She looked me in my eyes and told me very seriously "I hardly eat enough to stay alive". Omg lol. She believed that shit!!! I told her that wasn't true that she had stayed at my house before and she ate more than I did. She was silent then. Cause it's the truth and she knew it.  That level of complete and utter denial just blew my mind.
