Forgiveness for Nineveh

I once met a man in bank near USC who had the same name as me.  Our conversation did not get off to a good start, but he ended up coming to my mind years later when I reread the Book of Jonah.  We look at this parable, where a reluctant Prophet tries to flee God, spends three days and nights in the belly of a fish, and then goes on to learn a tough lesson about forgiveness.
