You surrender to Rostelli. You let yourself be dominated. And then everything goes automatically. When the ball begins to roll, there is no way back. If you have said A, you must also say B because Rostelli and the audience are waiting to hear it.
Some people begin to enjoy it and let themselves go totally.
They try to out-act each other and reep the success of doing so. They don't need to be afraid of justifying their actions afterwards because their friends and relatives believe they had no control over what they did. There are those who declare that they are unable to remember what they did on stage. This mostly comes about because they don't want to remember. I spoke to one person, for example, who was ashamed that he had appeared as a Chippendale.
