[Verse 1]
F              C
   Oh, to be young
F                C
  It sounds like so much fun
F                 C               Am
  Oh, the long wait For things to happen
F          C
   Expectancy
F                C           F
   And you, just waiting on me
          C                  Am       G
I wanna know what's in your plan...

[Chorus]
Am
If you're an ocean then
F
I wanna jump right in
C
If you're a hand grenade then
G
I'll pull the pin
Am
I'll wait right here all night
F
For you to let me in
C
And I'll run, run, run, run
G
Run right back to you I'll run

[Verse 2]
F                C
   Life's moving faster now
F               C                  F
   I'm older here but younger somehow
             C                     Am
Head full of fear and it makes me break
F                C
  Please let me find you
F                C                   F
  Please let me know just what you want
              C                       Am      G
Please let me see what you need me to be
 
[Chorus]
Am
  If you're an ocean then
F
  I wanna jump right in
C
  If you're a hand grenade then
G
  I'll pull the pin
Am
  I'll wait right here all night
F
  For you to let me in
C
  And I'll run, run, run, run
G
  Run right back to you I'll run

[Bridge]
Em                       Am
Oh if you could see in me
          F          G
You might be kinda scared
Em                     Am
 Oh if I could just believe
               F   G
You'll take me anywhere

[Chorus]
Am 
  If you're an ocean then
F 
  I wanna jump right in
C 
  If you're a hand grenade then
G 
  I'll pull the pin
Am
  I'll wait right here all night
F
  For you to let me in
C
  And I'll run, run, run, run
G
  Run right back to you I'll run
