Leaving, Confrontation, Confrontations about leaving, you get the idea.
There was an exercise we did in improv class wherein one actor would attempt to keep the other actor from leaving the room. I've always remembered this, as the one that wants to leave, can simply leave, therefore, whatever the first actor says must be pretty powerful.
I guest directed an acting class once, and they'd prepared scenes from various movies, and they all boiled downto something like this. One guy tried to leave the room, and I asked him why, and he replied, "Because that's what my character did in the film." My response, "Well, maybe he made a mistake!!!"
