My wife, seeing me getting ready for work after a night of basically zero sleep because I had to keep getting up to help her after her knee surgery: "How can you be awake and go to work? You must not have slept a bit, I know I didn't."
Me: "You merely adopted the insomnia. I was born in it, molded by it. I didn't see The Sandman until I was already a man, by then it was nothing to me but annoying!"
