Song lyrics Singled out by New Found Glory

I figured all the years we shared were proof enough
to extend my hand and help you
I know that getting started can be rough
Enthused smile, you seemed grateful
I felt real good about myself
That´s until the day you showed me
You needed anybody else

Why´d you have to go?
And make me say these things about you
Why´d you have to turn around?
After all that we´ve been through

I figured all the memories were proof enough
To maybe open your eyes
From the people you think hold your trust
Do you ever smile and find it shameful
´Cause you don´t know who you are?
I am glad you never told me...
You needed anybody else

What will you do
when there´s no one to fall back on?
I won´t be there
I´ve learned my lesson
What will you do when there´s no friends to fall back on?
Because they´ve all been stepped on
