 There goes my baby
 There goes my only one
 I think she loves me
 But she don't want to let on


 Yeah, she likes to keep me guessing
 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 like to leave me with a shadow of a doubt
 Oh!


 Sometimes at night, I
 Wait around 'til she gets out
 She don't like working
 She says she hates her boss


 But she's got me asking questions
 She's got me on defense
 With that little certain something
 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 running
 I'm trying to figure out
 If she's leading up to something
 Oh!


 And when she's dreaming
 Sometimes she sings in French
 But in the morning
 She don't remember it


 But she's got me thinking about it
 Yeah, she's got me on the edge
 With that little bit of mystery
 She's a complex kid
 And she's always been so hard to live without
 Yeah, she always like to leave me with a shadow of a doubt


 Well, a shadow of a doubt
 A shadow of a doubt
