The greatest thing I learned while taking classes at Second City was the very first thing they taught: 'Yes, and...'. In improv, you keep scenes alive but accepting whatever you are given and then adding to it or amplifying it. There is no space on stage for 'No,' 'I'm sorry, you're mistaken,' or 'Yes, but...'. Those transitions kill energy, set up interpersonal conflict, engage the ego in a defensive posture, and stymie the flow of conversation onstage.
