Adam and Jane spent three years on a NASA mission that had a major problem: their spacecraft broke down and drifted between Jupiter and Saturn. When they are convinced that no one will come to save them, they will try their best to pass the time and argue about what to do. One day, Adam posed and said, maybe they should sleep together; Jane laughed off the idea, but it sparked a frivolous debate about whether they were better off spending the remaining days as friends or doing more.
