 Tired of trying to figure out
 The space in me where you fit in
 You're in between where I fit in
 Do we end when I begin?
 Tired of trying to figure out
 The space in me where you fit in

 Do we end when I begin?

 Tired of trying to figure out
 The space in me where you fit in
 You're in between where I fit in
 Do we end when I begin?

 Tired of trying to figure out
 The space in me where you fit in

 Baby, don't you worry
 I was never holding my breath
 Mmm don't you worry
 I was never holding my breath

 Tired of trying to figure out
 The space in me where you fit in
 You're in between where I fit in
 Do we end when I begin?
 Waiting for nobody
 Feeling good alone in my bed
 Waiting for nobody
 Feeling good alone in my bed

 Tired of trying to figure out
 The space in me where you fit in
 You're in between where I fit in
 Do we end when I begin?
