I was hired to sit with a man the doctors said had five days left. One night I laid my teething baby on his chest — and his fingers moved. Then he whispered: don’t tell anyone I’m awake.

Completely conscious.

PART 2

I spent the rest of that night working out how to talk to him.

It took about forty minutes to build a system and we did it entirely with one eye.

I did not invent it. There is a version of it in the training, for stroke patients, and I had never used it once.

What I had to invent was the speed. He could hold that eye open for about four seconds at a time and then it closed whether he wanted it to or not.

So everything had to be a question with a yes or a no in it, which sounds simple and which took me two hours to get good at.

You cannot ask a man in that state what is happening to him. You can only ask him things you have already half worked out.

Which means the ceiling on that entire night was my own guessing, and there were things he was trying to tell me in the first hour that I did not get to for four days.

One blink is yes. Two is no. Looking at the door means somebody is coming.

That third one was his. He built it himself, on the first night, before I understood what he was doing — and it tells you what he had spent two months thinking about.
