"Bart, in your episode with Devin Moss you mentioned envying his role as a humanist chaplain for someone on death row, because he could throw himself into totally being there for that man, knowing it was only for a limited amount of time. That sounded easier to you than committing to love a needy person with lots of life ahead of them. That one strange comment has raised a lot of questions for me: Do we really have to be there for someone throughout every stupid thing they do? Why can't we just be there for an episode or two and then move on? Why can't somebody else step up once in a while? ... Obviously, we all have limited amounts of time, energy and emotional capacity. Essentially, I guess I'm asking: what do you think are the limits of our responsibilities to others?" Bart and John discuss.
