How could I share with you how I felt when two towers that I loved, two pieces of steel and glass and concrete fell down, when actually they took with them thousands of human lives? That is the actual tragedy. But those towers were almost human for me. I was in love with them, and that's why I married them with a tight rope.
I started making monkey bridges, like kids do, and climbing and rappelling with ropes. Very naturally, I needed some knots. At the very beginning, I didn't care, I didn't know, and then slowly I started to know, and I started to care. I wanted to know more knots or the right knot for the special action.
