KNOCK-KNOCK who's there?

While students were asked to perform this exercise in class, I noticed several things.
Reactions are not the same in front of an audience. Some people are forced to react concerning what it would be the best way to do so. Like we don't want to look bad in front of others.
We tend to fake our reactions in front of people. I believe that if that situation would have happened to somebody for real, they would have reacted in different ways.
You don't ask somebody that nicely to stop bothering you when you are un the middle of something and they don't want to leave you alone.
This exercise permitted us to see ourselves in those kind of situations. Most of us don't have the patience to hear somebody's problems when we are about to do something important.
The purpose of this exercise I think it was for us to become less aware of the public we had. Instead of using scenes from plays or saying a monologue, we used everyday tasks that happen to us normally without even rehearse them. This would make us think less of how we should say things or do them, it is just us being ourselves in front of spectators, wether or not that make us act different, we learn from it.
