Yes, but there's also something to be said for her decision NOT to fully retire; merely to fade into a bit of obscurity for a while. She has even promised to keep in touch with her fans. I think she's grown a lot since that interview took place and what she was saying then and what she says now is indicative of a very different perspective on life. I would say that the reasons she thought she would be retiring at 28 then and the reasons she's chosen to take a break at 28 now are not the same; the age happens to be convenient and consistent with her past statements, but the motive has changed.
