Well, you only need the light when it's burning low
              D                       Em
Only miss the sun when it starts to snow
               C                           G       D
Only know you love her when you let her go

Only know you've been high when you're feeling low
              D                          Em
Only hate the road when you're missin' home
               C                           G
Only know you love her when you let her go
D
  And you let her go

Staring at the bottom of your glass

Hoping one day you'll make a dream last

You see her when you close your eyes

Maybe one day you'll understand why

Everything you touch surely dies

Same old empty feeling in your heart
                    Em              C       D
'Cause love comes slow and it goes so fast

Well you see her when you fall asleep

And you dived too deep
