G (320003@1)                      A (x02220@1)Placing a smile at the perfect event,
              D (xx0232@1)                         BmGracing (x24432@1)your skin with the side of my hand,
             G (320003@1)                              A (x02220@1)If I ever leave, I could learn to miss you,
                D (xx0232@1)                   BmBut (x24432@1)sentimental boy as my nom de plume.

G (320003@1)            A (x02220@1)D (xx0232@1)          BmLet (x24432@1)me save you, hold this rope.

G (320003@1)           A (x02220@1)          D (xx0232@1)          BmAs (x24432@1)long as you're still burning bright,
G (320003@1)               A (x02220@1)If I could trade mistakes for sheep,
D (xx0232@1)              BmCount (x24432@1)me away before you sleep,
G (320003@1)                       A (x02220@1)I'll still wait 'til I trade my mistakes 
D (xx0232@1)               BmSo (x24432@1)they fade away.

           G (320003@1)              A (x02220@1)You can't fly these wings,
          D (xx0232@1)                      BmYou (x24432@1)can't sleep in this box with me,
