Doctor, this is why I love you. Right here.
Vincent van Gogh was a man who is somewhat famous for his mental instability. He later ended his own life. For the Doctor to go and show him that his art mattered, and that his existence mattered…is amazing. And I wish someone could have shown this amazing artist how much he contributed to the world.
I wish the Doctor could show everyone how they mattered, because everybody does matter. In our own small way, we change the world simply by existing.
