Was listening to a local radio station podcast while working out this afternoon and they were talking about role-playing scenarios with your spouse.
The Medicine Scenario was the one they discussed.
Synopsis:
You, your spouse, and two other married couples who are your friends, have all been exposed to a deadly, but curable disease. Each of you are given (2) pills that are the medicine that can cure the disease.
However, it takes (4) pills to cure the disease. (2) alone will not work.
