What's wrong with a Step Five that lasts 20 or 100 hours?
Are there exceptions?
So, does the detail ever get discussed?
If the sponsee would like to 'share with another person everything that has ever happened to him, everything he has ever thought and felt, and everything he has ever done, right or wrong,' a therapist can be hired or friends can be found. There likely is a need to talk, talk, and talk, but that's what fellowship and the rest of one's life are for. Also, every story will ultimately get retold when the individual acquires sponsees. That is a very good time for telling all the stories, because then the stories, combined with some insight, can prove useful to others.
