I tend to think that, "We are the protagonists in our own stories" - in many ways this is my cynical remark about how people broadcast their lives on the internet and the way they expect the world to fall in line around them. In another way, this reminds me that the people I interact with have built up themselves as a 'protagonist' and that if we have conflicts, perhaps I should be forgiving if they're totally ignorant and unwilling to see my point of view. And maybe, like a kitten that has been exposed to only horizontal lines for her whole life, this person is actually _unable_ to see vertical lines. Their story has been complex and personal, and their experiences totally different from mine. They need my patience and understanding instead of my ire.
I think that's the flip side to this card. The Protagonist continues to walk through life in a role he takes for granted. The message I get from this one is to question your story instead.
Been working through your cards over the last day, I may have to get myself a deck!
