Meeeeeeeeeeeeh I'm fine with non existence because who knows really if anything is real. Sure we can eat and breathe and think but who's to say that the entire world you know of and everything you have seen or will see is just a dream? But anyways time to go back to looking at random hilarious comics about the fourth wall.
Some people thinks twilight is staring at us because she understands the fourth wall, but I know the real truth: she heard "brony" in the prequel, searched it, and when Pinkie Pie posed the question, "Why do you think he became a fan of a show about little ponies?" She knows the answer... the "plot".
