(Repeat through verse)

Verse 1:
F              C
Oh, to be young
F              C
It sounds like so much fun
F
Oh, the long wait
C               Am
For things to happen
F          C
Expectancy
F             C
And you, just waiting on me

F         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
(Same as Verse 1)


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

Chorus
