We process internally all that is external. Especially, the people in our lives. Somehow we tie their behavior to our own grain and resort to judging them or ourselves.
What if each person was simply living life as a character in a book? would we be as inclined to judge or control a character in a book? perhaps not. As well, what if this external person is holding up a mirror for us to examine which part of ourselves is showing up as we perceive them and their life.
Interesting experiment to conduct, entertaining for sure.
