I don't understand
  You look just like the man
  In the picture by our bed
  The suspence is pounding and clouding up my head
  I'm checkin' your clothes
  And you wear the same size shoe
  You sleep in his spot
  And you're driving his car
  But I don't know just who you are
    There's a stranger in my house
  It took a while to figure out
  There's no way you could be who you say you are
  You gotta be someone else
  Cuz he wouldn't touch me like that
  And he wouldn't treat me like you do
  He would adore me, he wouldn't ignore me
  So I'm convinced there's a stranger in my house
    I'm not sure who you are
  Don't see your shadow around when you walk
  Ain't leavin' no kisses
  Goodbye with no words
  If these walls could talk
  They would have nothing to tell
    So what could it be?
  Is there someone immitating me?
  Could she be taking my place?
  Look me in the face
  And tell me that I'm wrong
  When I say...
    There's a stranger in my house
  It took a while to figure out
  There's no way you could be who you say you are
  You gotta be someone else
  Cuz he wouldn't touch me like that
  And he wouldn't treat me like you do
  He would adore me, he wouldn't ignore me
  So I'm convinced there's a stranger in my house
    Pop quiz
  Tell me where we first kissed
  Tell me where my spot is
  Tell me if I liked it, loved it
  Or could it be
  That the stranger is me
  Have I changed so drastically?
  Is it I want more for me?
  And you remain the same
    There's a stranger in my house
  It took a while to figure out
  There's no way you could be who you say you are
  You gotta be someone else
  Cuz he wouldn't touch me like that
  And he wouldn't treat me like you do
  He would adore me, he wouldn't ignore me
  So I'm convinced there's a stranger in my house
