With Noel, we're staying with some friends, the bedroom is in the attic. We climb some steep steps to the top floor then he steps out and walks along a white wall with a massive drop below. There's no path or ledge I can see, yet he walks along the wall. 'Are you going to do this right?' he asks. I'm terrified, at the other end is a tiny hole, the entrance to the bedroom. I step out.
