Disappearing Act

I disappear for a day, and you figure, She’s got a life, after all. She lives in Manhattan and eats food I’ve never heard of and wanders down streets I’ve only heard about in song.
I disappear for two days, and you decide, Trouble’s befallen her. She lives in Manhattan and that food I’ve never heard of is poison and she’s lying in a ditch alongside one of those wandered song-sung streets.
If I don’t show my lunch, it’s not that I haven’t eaten. If I don’t tell you where I go, it’s not because I haven’t gone anywhere. If I don’t divulge how I voted on American Idol, it’s not because I’m not watching.
A girl needs a little mystery after all, doesn’t she?
P.S. Thanks to whomever posted my bail! :-*
