It's a nice random collection of quotes, I'll give them that.
Keira's been talking about this for ages now, about wanting a break, wanting her life back. It sounds to me like they've just taken random quotes from all over the place.
In addition, wasn't she still filming for Pirates in November? Los Angeles studio stuff, or re-doing stuff in the Caribbean? I'm not entirely sure, but I think she's been off doing things. She's filmed the Chanel ad. She's doing her mum's film soon. She's apparently in negotiations for another film, the 1.something or other one. Doesn't sound like she's quitting to me. She might just be taking it a bit easier, which is completely understandable. The lady has been crazy busy
