PRE VERSE= F/// C/ A#/

VERSE 1
F                C
Stepping off the ledge
             A#
She looks at me and says
                F
Hey Tommy can I spend the night
    C               A#
And wake up in your eyes
F
Of course you can, timidly answered,
C
But beware I can't promise much
A#
Not at this time in my life

CHORUS
F
Watching trees change
C
Just like your ways
D                 A#
You're in my arms for the last time
F
Pressed together
C
My heart's weathered
D                 A#
Now we will sleep for the last time

VERSE 2
F                  C
I build you up and break myself down
AH#                            F
How can I sit there while some clown
                C            A#
Namely me, Sets you up for a loss
F
First of all I'm insecure
    C                               A#
And number two I can't be there for you
Not at this time in my life
