A               D           E
i've learned to slam on the brake
A        D    E
before i even turn the key
A        D        E
before i make the mistake
A        D              F#m     E
before i lead with the worst of me
A            D         E
give them no reason to stare
A           D   E
no slippin up if you slip away
A        D         E
so i got nothin to share
A            D          F#m E
no, i've got nothing to sa-ay

[Pre-Chorus]
Bm             F#m          E
 step out, step out of the sun
       A            D
if you keep getting burned
Bm             F#m          E
 step out, step out of the sun
A              D
because you've learned
E
because you've learned

[Chorus]
F#m            D
on the outside always looking in,
       A            E
will i ever be more than i've always been
           F#m                    D
'cause i'm tap-tap-tapping on the glass
    A                E
i'm waving through a window
 F#m                D
i try to speak but nobody can hear
     A                  E
so i wait around for an answer to appear
          F#m                         D
while i'm watch-watch-watching people pass
    A                E
i'm waving through a window, oh
F#m           D
  can anybody see
           E
is anybody waving
A       D    E
back at me
A  D  E

[Verse 2]
A               D           E
we start with stars in our eyes
A        D              E
we start believing that we belong
A        D            E
but every sun doesn't rise
A          D               F#m      E
and no one tells you where you went wrong

[Pre-Chorus]
Bm             F#m          E
 step out, step out of the sun
       A            D
if you keep getting burned
Bm             F#m          E
 step out, step out of the sun
A              D
because you've learned
F#m            E
because you've learned

[Chorus]
F#m            D
on the outside always looking in,
       A            E
will i ever be more than i've always been
           F#m                    D
'cause i'm tap-tap-tapping on the glass
    A                E
i'm waving through a window
 F#m                D
i try to speak but nobody can hear
     A                  E
so i wait around for an answer to appear
          F#m                         D
while i'm watch-watch-watching people pass
    A                E
i'm waving through a window, oh
F#m           D
  can anybody see
           E
is anybody waving

[Bridge]
            F#m          D
when you're falling in a forest
            E      A
and there's nobody around
       F#m         D
do you ever really crash
        E       A
or even make a sound
            F#m          D
when you're falling in a forest
            E      A
and there's nobody around
       F#m         D
do you ever really crash
        E       A
or even make a sound
            F#m          D
when you're falling in a forest
            E      A
and there's nobody around
       F#m         D
do you ever really crash
        E       A
or even make a sound
            F#m          D
when you're falling in a forest
            E      A
and there's nobody around
       F#m         D
do you ever really crash
        E       A
or even make a sound
      F#m
did i even make a sound
      D
did i even make a sound
            A
it's like i never made a sound
       E
will i ever make a sound

(Important (kind of)!! There is a key change here from A major to G minor. The chord progression changes.
This might take a little getting used to. Just thought you should know.)

[Chorus]
Gm             Eb
on the outside always looking in,
       Bb           F
will i ever be more than i've always been
          Gm                      Eb

i'm waving through a window
  Gm               Eb
i try to speak but nobody can hear
     Bb                 F
so i wait around for an answer to appear

i'm waving through a window, oh

Bb      Eb
back at me

[Outro]
