Writer James Frey (a.k.a., "the next Dave Eggers;" author of A Million Little Pieces) in an interview with Zulkey.com on jail and rehab: "Jail is really fucking boring, and occasionally, really fucking scary. It is about doing time and getting it over with and staying out of trouble. Rehab is about fixing and changing your life. It, however, can also be boring and scary."
