Tom Petty & The Heartbreakers shadow of a doubt a complex kid

There goes my baby, there goes my only one
I think she loves me, but she don't wanna let on
Yeah, she likes to keep me guessin', she's got me on the fence
With that little bit of mystery, she's a complex kid
And she's always been so hard to figure out
Yeah, she always likes to leave me with a shadow of a doubt
Sometimes at night I wait around 'til she gets out
She don't like workin', she says she hates her boss
But she's got me askin' questions, she's got me on the fence
With that little certain somethin', she's a complex kid
And she's always been so hard to get around
Yeah, she always likes to leave me with a shadow of a doubt
Just a shadow of a doubt, she seldom keeps me runnin'
I'm tryin' to figure out if she's leadin' up to somethin'
And when she's dreamin', sometimes she seems depressed
But in the morning, she don't remember it
But she's got me thinkin' 'bout it, yeah, she's got me on the fence
With that little bit of mystery, she's a complex kid
And she's always been so hard to live without
Yeah, she always likes to leave me with a shadow of a doubt
With a shadow of a doubt, a shadow of a doubt
