Going along with the idea of "Better now that you're here" i wanted to have an exercise that would promote a positive attitude towards a new presence or information.
One that came to mind was the improv exercise, "It's Monday." In this, two people start on stage, one begins the scene by delivering some mundane or ordinary information such as, "It's Monday." The other person responds at an energy level of ten, as if that is life changing information, and the scene continues from there.
To focus on the positive attitude, I will add a distinction. In the original exercise, the one responding can do so however they wish, as long as it's at a level ten. But, i purpose a rule in which they can only respond with a positive reaction. However mundane or normal the given initiation is, the one responding must give a level ten reaction that is considered positive in nature.
This can be made more difficult by having the initiation be something that could be considered negative, but the responder still spinning it to make their reaction positive.
