It's not difficult, sir. It is simple. Burke is not here. He's gone, and he's the better for it. He's winning the Harper-Avery award, and being celebrated all over the world. That's not difficult. He's out there, and I'm here, where everything is the same. I still live in his apartment, I walk the same halls of this hospital, I wear the same scrubs. So, even that is not difficult. This is where I am. This is where I choose to be.
