I stand in front of the audience, with my large pair of glasses on the floor nearby. Slowly, I move towards somebody in the audience and stop. When we are almost touching noses, I look the person straight in the eye. Sometimes I have to stand on tiptoe if the person is very tall. To look into the eyes of those who are seated, I have to crouch down. As soon as I have looked at everybody, I return to my place. I look for my glasses, and then put them on, I smile...
