Verse 1
        C                  Am
it's a shame tapping on my windowpane
        C               Am
it's a shame never goes away
        C                  G
it's a shame oh but it's a gentle rain 
         Dm                      F
it's a shame it's a shame it's a shame shame shame

Verse 2
           C                 Am
we're the same wonder why we go insane
           C                      Am
we're the same thats just how we're made
           C                G
we're the same oh but in a different way
         Dm                      F
it's a shame it's a shame it's a shame shame shame

PreChorus
G

hiding each other

hiding each other
Am G
those young lovers
Am              F
only ones who know

Chorus
C       Dm             Am
I would dive into your love
                  G
and I would go as deep
C      Dm
as my lungs would let me
   Am                   G    F
if I were to marry the sea
