The XX Factor: What women really think.

Will Chris Brown's Apology Stick?

Chris Brown has a thing or two to teach Mark Sanford and John Ensign about how to say you're sorry. In his taped apology to Rihanna, for punching her in February, the singer sounds forthright and sincere. He's straightforward and direct. He invokes his mother, more than once. He says he's getting help and he promises not to do it again. All the boxes checked, including remorse.
